Questions
A reaction is first order in A and second order in B. How is the rate affected on increasing the concentration of B three times?
A reaction is of first order with respect to reactant [A] and second order with regard to reactant [B]. What is the effect on rate of reaction when concentration of [B] three times?

Solution
If the concentration of B is increased three times, then:
`-(d[R])/dt` = k[A][3B]2
= 9k[A][B]2
∴ The reaction rate will increase by a factor of 9.

Why is the probability of reaction with molecularity higher than three very rare?
Assertion: Order and molecularity are same.
Reason: Order is determined experimentally and molecularity is the sum of the stoichiometric coefficient of rate determining elementary step.
Assertion: The enthalpy of reaction remains constant in the presence of a catalyst.
Reason: A catalyst participating in the reaction, forms different activated complex and lowers down the activation energy but the difference in energy of reactant and product remains the same.
Assertion: Rate constants determined from Arrhenius equation are fairly accurate for simple as well as complex molecules.
Reason: Reactant molecules undergo chemical change irrespective of their orientation during collision.
