Question

what is first order reaction ? give two examples of first order reaction obtain an expression for the rate constant of a first order reaction​

Answer 1

Answer:

A first-order reaction depends on the concentration of only one reactant. As such, a first-order reaction is sometimes referred to as a unimolecular reaction. While other reactants can be present, each will be zero-order, since the concentrations of these reactants do not affect the rate. For a first order process A→B rate constant k1=0. 693 min−1 and another first order process C→D, K2=x min−1. If 99. 9% of C→D requires time same as 50% of reaction A→B, value of x? (in min−1)
