Substances which alter the velocity of a...

Substances which alter the velocity of a reaction by mere presence, without undergoing any change in mass and composition are termed catalysts and the phenomenon is known as catalysis.
In homogenous catalytic reactions, there are three alternative paths A, B and C (shown in figure). Which one of the following indicates the relative case with which the reaction can take place?

A

`A gt B gt C`

B

`C gt B gt A`

C

`B gt C gt A`

D

`A = B = C`

Text Solution

Verified by Experts

The correct Answer is:
B
Activation energy in the different path lies in the following sequence:
`C lt B lt A`
Lesser is the activation energy, greater is the case with which the reaction can take place.
`therefore C gt B gt A` (Decreasing ease with which the reaction can take place.)

The reaction A rarr X is a first order reaction which takes place in a vessel with initial concentration of A as 10 M. The rate constant for this reaction is 4.16 h^(-1) . In the presence of a catalyst, the reaction A rarr Y follows second-order kinetics and the rate constant is 0.2 min^(-1) M^(-1) . What should be the initial concentration of A in the presence of catalyst so that the value of t_(1//2) for both the reactions is the same?
