What causes numerator of a expression to equal zero?
When the numerator of any expression or fraction is zero then the result is zero because zero divided by any number is always equal to zero.
When a denominator is zero is the expression undefined?
That is correct.
Why is the denominator set to zero to graph a rational expression?
When the denominator is equal to zero, the expression is undefined. Close to those places, the expression tends towards plus infinity, or minus infinity. In other words, setting the denominator to zero will tell you where there are vertical asymptotes.
What can't you have in the denominator?
A zero. Zero in the denominator make the expression undefined for algebraic purposes.
What are the two conditions that will show an expression considered as an absolute value?
You must look at the condition when the expression is greater or equal to zero and the case (condition) when it is less that zero.
What is the rate law for a zero-order reaction?
The rate law for a zero-order reaction is rate k, where k is the rate constant. In a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants.
What is the relationship between the rate law and zero order in a chemical reaction?
In a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants. The rate law for a zero-order reaction is rate k, where k is the rate constant. This means that the rate of the reaction is constant and does not change with the concentration of the reactants.
What is the rate constant for this zero-order reaction?
The rate constant for a zero-order reaction is a constant value that represents the rate at which the reaction proceeds, regardless of the concentration of reactants.
What is the rate law expression for a first-order reaction?
The rate law expression for a first-order reaction is: Rate kA, where Rate is the reaction rate, k is the rate constant, and A is the concentration of the reactant.
What is the zero order rate law equation and how does it relate to the rate of a chemical reaction?
The zero-order rate law equation is Rate k, where k is the rate constant. In a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants. This means that the rate of the reaction remains constant over time, regardless of changes in reactant concentrations.
What is the rate constant for a zero-order reaction?
The rate constant for a zero-order reaction is a constant value that represents the rate at which the reaction proceeds, regardless of the concentration of reactants. It is typically denoted as "k" and has units of concentration/time.
How do you calculate the half life of a zero order reaction?
For a zero order reaction, the half-life is calculated using the equation: t1/2 = [A]0 / 2k, where [A]0 is the initial concentration of the reactant and k is the rate constant of the reaction. The half-life is independent of the initial concentration of the reactant in zero order reactions.
What is the order of photoelectric reaction?
The order of the photoelectric reaction is zero order because the rate of the reaction does not depend on the concentration of the reactants. The rate is solely determined by the intensity of the incident light.
How can one determine the order of reaction from a graph?
To determine the order of reaction from a graph, you can look at the slope of the graph. If the graph is linear and the slope is 1, the reaction is first order. If the slope is 2, the reaction is second order. If the slope is 0, the reaction is zero order.
Why zero order reaction depends upon light?
A zero-order reaction is independent of the concentration of reactants and proceeds at a constant rate. Light can influence the rate of a zero-order reaction by providing the activation energy needed for the reaction to occur. In some cases, light can also act as a catalyst, speeding up the reaction without being consumed itself.
If the order of a chemical reaction with respect to one of its reactants is zero how does that reactant's concentration affect the rate of the chemical reaction?
If the order of a reactant is zero, its concentration will not affect the rate of the reaction. This means that changes in the concentration of the reactant will not change the rate at which the reaction proceeds. The rate of the reaction will only be influenced by the factors affecting the overall rate law of the reaction.
What is the order of the reaction with respect to clo2?
The order of a reaction with respect to ClO2 is determined by the exponent of ClO2 in the rate law expression. If the rate law is of the form rate = k[ClO2]^n, then the order with respect to ClO2 is n. This value can be determined experimentally by measuring how changes in the concentration of ClO2 affect the reaction rate. If the concentration of ClO2 does not appear in the rate law, then the order with respect to ClO2 is zero.
