Factors Affecting the Rate of a Chemical Reaction

How much of ...

Question

How much of $N_{2} O$ will decompose in $100$ min. at the same temperature but at initial pressure of $600$ mm?

Open in App

Solution

(i)In the case of gases, pressure can be synonymous with concentration.
(ii) The given question shows a first order reaction. In first order reactions, the time required to complete any part of the reaction is independent of the initial concentration of reactant.
(iii) Therefore a change in initial pressure will not affect % decomposition of $N_{2} O .$ It will still be $73 %$ .
