Question

Define half-life of a reaction. Write the expression of half-life for 

(a) zero order reaction 

(b) First order reaction

Answer 1

Half-life is defined as the time taken for half of the reaction to complete. 

(a) Half-life for zero order reaction = \(\frac{[R_o]}{2k}\)

(b) Half-life for first order reaction = \(\frac{0.693}{k}\)
