Chemical Kinetics MCQ For NEET PDF (Collision Theory of Chemical Reactions)

31. What is the unit of rate constant for first order reaction?

Ans. Sec or minute

32. What is activated complex?

Ans. It is the unstable transition state of the reactant with highest energy equal to threshold energy.

33. What is zero order reaction ?

Ans. The reaction in which rate of reaction is independent of concentration of the reactant is called as
zero order reaction.
e.g. H2 +Cl 2HC1

34. What is the order of the reaction given below? 2N2O5→ 2N2O4 +0

Ans. It is a Ist order reaction.

35. Give an example of 1st order reaction

Ans. PCI, PCI, + ClL
Experimentally found, Rate K [PCi]
So order of reaction=1
Rate of reaction is directly proportional to 1st power
of the concentration of reactant.

36. Write the integrated rate equation for 1st order reaction.
    Ans. 2.3031og
    Where K = rate constant of the reaction.
    a initial amount of reactant.
    x amount decomposed in time ‘t
37. If the rate constant of a reaction is same as the rate of reaction at any concentration of reactant, what is the order of reaction ?

Ans. Zero order reaction

38. Give an example of fractional order reaction
    Ans. CH,CHO CH, +CO Rate K[CH,CHO order of the above reaction = 1.5
39. For a reaction half life period is independent of initial concentration of reactant. What is the order of reaction 2

Ans. First order reaction

40. Rate constant of a reaction depends upon.

Ans. temperature
