Calculate the half-life of the reaction

Answer:
Half-Life of a Reaction
The mathematical expression can be employed to determine the half-life for a zero-order reaction is, t1/2 = R0/2k.
For the first-order reaction, the half-life is defined as t1/2 = 0.693/k.
And, for the second-order reaction, the formula for the half-life of the reaction is given by, 1/kR0
