  1. The reaction A + 2B 2C obeys the rate equation: Rate = KAB What is the order of the reaction?

Ans. Order =+3/2 =2

  1. What is photochemical reaction ?

Ans. The reaction whose rate is influenced by light radiation is called as photochemical reaction.
e.g. photosynthesis, decomposition of H,O,.

  1. For a zero order of reaction the concentration.

Ans. Varies directly with

  1. How does rate of zero order reaction vary with progress of time ?

Ans. Rate of a zero order reaction remaians unchanged with progress of time. t, C

  1. For ‘n’ th order reaction,

Ans. ca-n/2

  1. For a zero order reaction, the molecularity is zero. Yes or no

Ans. No, moleculararity of a reaction can never be Zero.
E2

  1. In the equation K – Ae RT, what is A

Ans. A is a constant called as collision number or frequency factor and its unit is sec

  1. How does the value of K’ vary with activation energy ?

Ans. As the value of activation energy increases the rate constant (K) value decreases. (As given in Arrhenius equation)

  1. Can all molecular collisions yield the product ?

Ans. No, only the effective collisions yield the
product.

  1. What is the condition when all collisions between the molecules can be effective collision ?

Ans. When activation energy of the reactant is zero,
then K= A. Where K rate constant A = collision number.
Under such conditions all collisions can be effective
collision to form the product, But this concept 1s
theoritical.

  1. What is the unit of zero order reaction

Ans. Mol lit sec .

  1. Write two factors which influence rate constant of a reaction ?

Ans. Temperature and catalyst.

  1. The ratio between the rate constants at two different temperature differing by 10°C is called

Ans. Temperature co-efficient

  1. For a 1st order reaction when rate of reaction is platted conc. of reactant a straight line is obtained whose slope is 2.5. What is its rate constant.

Ans. Rate constant = slope = 2.5 Sec
