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 is the thing in trig called that has a letter in the center and double vertical lines on both sides?
Double verticle lines surrounding an expression means to take the absolute value of the expression. The absolute value of an expression is the expression if it is positive, and the negative of the expression if it is negative, i.e. the unsigned distance from zero. Analytically, in order to process the expression, the absolute value of an expression is also the square root of the square of the expression.
What can't you have in the denominator?
A zero. Zero in the denominator make the expression undefined for algebraic purposes.
Why photochemical reaction is zero order reaction?
Because it depends upon light.
How is order of reaction determined graphically?
in our syllabus there is only the first and the zero order reaction in which if the graph is plotted between the concentration and time then it is a zero order reaction while if the graph is between the log of concentration and time then the reaction is of the first order.hope this will help u.
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?
It doesn't - the reaction rate will not change regardless of how much of that reactant is added. That's the definition of zero-order.
What is the unit of first order reaction?
A zero-order reaction is a reaction that proceeds at a rate that is independent of reactant concentration. Typically with increasing or decreasing reactants
What expression has a value of either true or false?
In C, any non-zero expression is true and any zero expression is false.
Why zero order reaction depends upon light?
Because it depend upon light
What happens to the reaction rate as the reaction gets used up?
The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.
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.
What is the k in the rate law equation?
A rate constant
What is The order of reaction for which unit of rate and rate constant is same?
In a zero order overall process, the rate and rate constant will be the same. (Reaction order is an exponent, and if that exponent is "0" then the value is "1" and will cancel out.)
How is the effect of concentration changes on the reaction rate seen in the rate?
That depends on the order of the reaction. If the reaction is zero order with respect to a reactant, then changing the concentration will have no effect on rate. If it is first order, then doubling the concentration will double the rate. If it is second order, then doubling the concentration will quadruple the rate.
How do you identify whether the order of the reaction is zero order first order or second order?
Linear system of arbitrary complexty can be viewed as being composed of first and second order
