Question

what is the unit of rate constant incase of 1st,2nd and 3rd order reaction​

Answer 1

Answer:

if the reaction is second order, then two units of concentration are already present so the rate constant needs reciprocal time plus inverse units of concentration, L mol-1 s-1. If the reaction is third order, the rate constant should have units of L2 mol-2 s-1.

Answer 2

Answer:

The order of the reaction is second, and the value of k is 0.0269 M-2s-1. Since the reaction order is second, the formula for t1/2 = k-1[A]o-1. This means that the half life of the reaction is 0.0259 seconds.
