Molecularity refers to the number of reactant molecules involved in a single elementary reaction step. Since a reaction must involve at least one molecule colliding to initiate a process, molecularity cannot be zero. A molecularity of zero would imply no reactants are participating, which contradicts the fundamental definition of a chemical reaction. Therefore, the minimum molecularity is one, representing a unimolecular reaction.

Why order is zero while molecularity is not zero?

Molecularity can only have integer values(1,2,3...).So,its value canot be zero.It can be calculated by simply adding the molecules involved in a chemical reaction.


What are the differences between order and molecularity of a reaction?

ORDER OF A REACTIONMOLECULARITY OF A REACTIONIt is sum of the concentration terms on which the rate of reaction actually depends or it is the sum of the exponents of the concentrations in the rate law equation.It is the number of atoms, ions or molecules that must collide with one another simultaneously so as to result into a chemical reaction.It need not be a whole number i.e. it can be fractional as well as zero.It is always a whole number.It can be determined experimentally only and cannot be calculated.It can be calculated by simply adding the molecules of the slowest step.It is for the overall reaction and no separate steps are written to obtain it.The overall molecularity of a complex reaction has no significance. It is only slowest step whose molecularity has significance for the overall reaction.Even the order of a simple reaction may not be equal to the number of molecules of the reactants as seen from the unbalance equation.For simple reactions, the molecularity can usually be obtained from the Stoichiometry of the equation.Email: Shoaibbilal64@yahoo.com


Why every action has reaction?

Every action has an equal and opposite reaction to achieve Equilibrium where the forces sum to zero.


What is the k in the rate law equation?

A rate constant


Can the equilibrium constant equal zero?

No, the equilibrium constant (K) cannot equal zero. A zero equilibrium constant would mean that the reaction does not proceed in either direction, which contradicts the fundamental nature of chemical reactions to reach an equilibrium state.


When a reaction reaches equilibrium A ΔGo is equal to zero B ΔG is equal to zero C no substrate is converted to product D no product can be converted back to substrate E the reaction becomes?

When a reaction reaches equilibrium, B ΔG is equal to zero. This means that the Gibbs free energy change for the reaction is no longer driving the forward or reverse reaction, indicating a balance between the concentrations of reactants and products. However, substrates can still be converted to products and vice versa, so options C and D are incorrect. The reaction does not "become" anything specific, as it simply maintains a dynamic equilibrium.


What is the sum of action and reaction on a body and explain?

The sum of action and reaction on a body is zero according to Newton's third law of motion. This law states that for every action, there is an equal and opposite reaction. This is because the action and reaction forces act on different objects, resulting in a net force of zero on the system as a whole.


Is zero less than or equal to zero?

Zero is equal to zero


Solve 8x to the zero power?

Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.


What is the expression for equilibrium?

The expression for equilibrium is when the rate of the forward reaction is equal to the rate of the reverse reaction and the concentrations of reactants and products remain constant over time. Mathematically, it can be represented as: [ \text{rate}{\text{forward}} = \text{rate}{\text{reverse}} ]


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.


If for every action there is an equal reaction how does motion occur when the net force is zero?

The motion of an object upon which the net force is zero exhibits zero acceleration. The object's speed is a constant ... which may be zero ... and the motion is in a straight line
