Question

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

Answer 1

Answer:

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)

Answer 2

A chemical reaction in which the rate of reaction is directly proportional to the concentration of the reacting substance.

If reaction is,                        A→B

                             Rate of reaction ∝ [A]

examples:

• The hydrolysis of aspirin and the reaction of t-butyl bromide with water to give t-butanol.

• The hydrolysis of the anticancer drug cisplatin.
