Temperature coefficient of a reaction is 2 . When temperature is increased from 30^ C to 100^ C , rate of the reaction increases by

Options

  1. A128 times
  2. B100 times
  3. C500 times
  4. D250 times

Correct answer

A. 128 times

Step-by-step solution

For every 10^ C rise in temperature, rate increase by 2 times i.e., array ll & r₁=2^ n r where, & n= t 10 = 100-30 10 =7 & r₁=2⁷ r r₁=128 r array
