What is the order of a chemical reaction in which doubling the initial concentration of the reactants doubles the half life time of the reaction ?
Correct answer: A. 0
- A. 0
- B. 1
- C. 2
- D. 3
Explanation
For a zero-order reaction, the half-life is t1/2 = CA0/(2k), so doubling the initial concentration doubles the half-life. First-order half-life is independent of initial concentration, which is the common trap.

The reaction A → B is conducted in an adiabatic plug flow reactor (PFR). Pure A at a concentration of 2 kmol/m3is fed to the reactor at the rate of 0.01 m3 /s and at a temperature of 500 K. If the exit conversion is 20%, then the exit temperature (in k) is (Data: Heat of reaction at 298 K = - 50000 kJ/ kmole of A reacted Heat capacities CPA = CPB = 100kJ/kmole.
