Question

Identify the order for the following reactions 

1. Rusting of Iron 

2. Radioactive disintegration of ₉₂U²³

3. 2 A+ B → products; rate = k [A]^1/2 [B]²

Answer 1

Theoritically order value may be more than one but practically one. 

2. All radioactive disintegrations are first order reactions

3. 2A + 3B → products: 

rate = k[A]^1/2 [B]²

Order = \(\frac{1}{2}\) + 2 =  \(\frac{5}{2}\)  2.5
