Given examples for first order reaction.

Explanation

(i) All radioactive transformations follows first order kinetic. For example,
`._(92)U^(238)rarr ._(90)U^(234)+ ._(2)He^(4)`
(ii) Decomposition of sulphuryl chloride in the gas phase proceeds by first order kinetics.
`SO_(2)Cl_(2(g))rarr SO_(2(g))+Cl_(2(g))`
(iii) Inversion of sucrose in acidic aqueous medium follows first order reaction.
`C_(12)H_(22)O_(11)+H_(2)O overset(H^(+))rarr C_(6)H_(12)O_(6)+C_(6)+C_(6)H_(12)O_(6)`
