Slope of the graph between [ A ]₀ [ ~A ]_ t (y axis) and time ( x axis) for first order reaction is equal to:

Options

  1. Ak 2.303
  2. Bk
  3. C- k
  4. D- 2.303 k

Correct answer

A. k 2.303

Step-by-step solution

The integrated rate law for the first order reaction is gathered k= 2.303 t ₁₀ [ A ]₀ [ ~A ]_ t ₁₀ [ A ]₀ [ ~A ]_ t = k 2.303 t y m x gathered The graph of ₁₀ [ A ]₀ [ ~A ]_ t versus time ( t ) is a straight line passing through origin with slope ( m )=+ k 2.303
