For a reaction r=k[A][B]^2 , if concentration of A is doubled the rate of reaction

Options

  1. Aincreases by 2
  2. Bdecrease by 1 2
  3. Cincreases by 4
  4. Ddecreases by 2

Correct answer

A. increases by 2

Step-by-step solution

aligned & Rate = k [ ~A ][ B ]^2 & ( Rate )₂= k [2 ~A ][ B ]^2= k 2[ ~A ][ B ]^2 & ( Rate )₂=2 Rate aligned i.e., rate of reaction increases by a factor of 2 .
