Question

Write the equation for integrated rate law for a first order reaction.

Write the integrated rate equation for a first order reaction.

Answer 1

The integrated rate equation for a first order reaction can be represented· in the following forms.

[A] = [A]₀ e^−kt

k = `2.303/t. log_10  ([A]_0)/([A]_t)`

`k = 2.303/t log_10 a/(a - x)`

where,

[A]₀ is the initial concentration of the reactant A at time t = 0, [Al_t is the initial concentration of the reactant A at time t = t.
