For the reaction, A → Products, it is found that the rate of reaction increases by a factor of 6.25, when the concentration of 'A' is increased by a factor of 2.5. The order of reaction with respect to A is
Options
- A2.5
- B2
- C1
- D0.5
Correct answer
B. 2
Step-by-step solution
Rate = k [ A ] n = k ( x ) n So 6.25 × R a t e = k ( 2.5 x ) n or 6.25 × k ( x ) n = k ( 2.5 x ) n or 2.5 x x n = 6.25 i.e., ( 2.5 ) n = ( 2.5 ) 2 or n = 2 .
