What is the value of rate constant for first order reaction if slope for the graph of rate versus concentration is $2.5 \times 10^{-3}$ ?
  1. $2.5 \times 10^{-3}$ time $^{-1}$
  2. $5.0 \times 10^{-3}$ time $^{-1}$
  3. $7.5 \times 10^{-3}$ time $^{-1}$
  4. $1.25 \times 10^{-3}$ time $^{-1}$

Solution

For a first order reaction, $\therefore \quad$ Rate constant $(\mathrm{k})=2.5 \times 10^{-3}$ time $^{-1}$
