Explanation:

  • So we have k as constant rate, t is time taken = 10 seconds, m is initial concentration and m – x is concentration of substance reduced to half = m/2
  • So the law of first order kinetics is  k = 2.303 / t log m/m – x
  • So k = 2.303 / 10 log m / m/2
  • So k = 2.303 / 10 log 2
  • Or k = 0.1596 / sec
  • So the rate constant for the reaction is 0.1596 / sec
