MCQ
Which of the following expression is correct for first order reaction? $(CO)$ refers to initial concentration of reactant
- A${t_{1/2}} \propto CO$
- B${t_{1/2}} \propto C{O^{ - 1}}$
- C${t_{1/2}} \propto C{O^{ - 2}}$
- ✓${t_{1/2}} \propto C{O^0}$
✓
Answer
Correct option: D.
${t_{1/2}} \propto C{O^0}$
d
(d)${t_{1/2}} \propto {(CO)^o}$ i.e. half life for Ist order is independent of initial concentration.
