For reaction a A x P , when [A]=2.2 mM , the rate was found to be 2.4 mM s . On reducing concentration of A to half, the rate changes to 0.6 mM s ⁻¹ . The order of reaction with respect to A is
Options
- A1.5
- B2.0
- C2.5
- D3.0
Correct answer
B. 2.0
Step-by-step solution
a A x P Rate of reaction =[A]^a Order of reaction =a . [A]₁=2.2 mM , r₁=2.4 ~m M s ⁻¹[A]₂= 2.2 2 mM , r₂=0.6 mM s ⁻¹ or, 2.4 4 On reducing the concentration of A to half, the rate of reaction is decreased by four times. Rate of reaction =[A]^2 Order of reaction =2 .
