Half life period of the first order reaction depends upon:

Correct answer: B. Temperature

  • A. Initial concentration
  • B. Temperature
  • C. Catalyst
  • D. All of above

Explanation

1st order reactionHalf life time - t1/2 = 0.693/kK = rate constantK is dependent on temperature So, t1/2 is also dependent on temperature.

About Reaction Kinetics

Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
