The Arrhenius equation describes the relation between the rate of reaction and temperature for many physical and chemical reactions
It is an expression that provides a relationship between the rate constant (of a chemical reaction), the absolute temperature.
The Arrhenius equation,
k = , where
k is the rate constant,
z is the collision factor,
p is the steric factor,
Ea is the activation energy,
R = 8.3245 is the ideal gas constant, and,
T is the temperature.
The activation energy by definition, is the minimum energy (or threshold energy) required for two particles of reactants upon collision to form products.
The Arrhenius equation could also be written as:
⇒ k = , where
⇒ A = zp, the Arrhenius factor.
Taking the neutral logarithm of both parties, we get:
⇒ In k = + In A,
Assuming that, A is independent of temperature, when T is increased, the equilibrium constant k will also increase and therefore, the rate of the reaction will also increase.

Answer : (b) The rate law expression for the reaction is:
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
The general reaction is:
The general rate law expression for the reaction is:
where,
a = order with respect to A
b = order with respect to B
R = rate law
k = rate constant
and
= concentration of A and B reactant
Now we have to determine the rate law for the given reaction.
The balanced equations will be:
In this reaction, and
are the reactants.
The rate law expression for the reaction is:
or,
