Question

Match the following
Order of reaction Half-life period
1)1st order reaction a) $(k{a}_0{)}^{-1}$
2) Second order reaction b) $\frac{0.693}{k}$
3) Zero order reaction c) $\frac{a_0}{2k}$

• A. 1-a ,2-b,3-c
• B. 1-b,2-a,3-c
• C. 1-b,2-c,3-a
• D. 1-c,2-b,3-a

Answer 1

The correct option is B 1-b,2-a,3-c

Order of reaction Half-life period
1)1st order reaction - $\frac{0.693}{k}$
2) Second order reaction - $(k{a}_0{)}^{-1}$
3) Zero order reaction - $\frac{a_0}{2k}$
