The reaction 2 ~A + B + C D + E is found to. be first order in A , second order in B and zero order in C . What is the effect of increasing concentration of all reactants twice?

Options

  1. ARate of reaction increases 8 times.
  2. BRate of reaction increases 24 times.
  3. CRate of reaction increases 36 times.
  4. DRate of reaction remains unaffected.

Correct answer

A. Rate of reaction increases 8 times.

Step-by-step solution

aligned & Rate = k [ ~A ][ B ]^2[ C ]^0 & ( Rate )₁= k [2 ~A ] [2 ~B ]^2 [2 C ]^0 & =8 k [ ~A ][ B ]^2[ C ]^0 & ( Rate )₁ Rate = 8 k [ ~A ][ B ]^2[ C ]^0 k [ ~A ][ B ]^2[ C ]^0 =8 & ( Rate )₁=8 Rate aligned i.e., rate of reaction increases 8 times.
