Question

derive an expression for 1 st order reaction and half life period
​

Answer 1

Answer:

Half-Life Formula

t1/2 is the half-life of the reaction (unit: seconds) [R0] is the initial reactant concentration (unit: mol. L-1 or M) k is the rate constant of the reaction (unit: M(1-n)s-1 where 'n' is the reaction order)
