EXPERIMENT $4$: DETERMINATION OF THE RATE EQUATION FOR THE ACETON$-$IODINE REACTION

The reactant concentration of a first$-$order reaction taking place at $300$ K after $5000$ seconds

drops by half. When the same reaction occurs at $310$ K$,$ the reactant concentration decreases for $1000$ seconds.

Eventually it drops by half. According to this;

a$)$ Rate constant for the reaction at $300$ K$,$

b$)$ The time required for the reactant concentration to decrease to $$ of the initial value at $310$ K$,$

c$)$ and calculate the activation energy of the reaction.
