Statement-1 : Time taken for the completion of 75% of a Ist order reac...
Ime taken for the completion of 50% of the reaction.

Statement-2 : In a first order reaction, the time taken for the completion of 75% of the reaction is equal to 3 times the time taken for the completion of 50% of the reaction.

Both statements are incorrect.

In a first-order reaction, the time taken for the completion of a certain percentage of the reaction is not directly related to the percentage itself. The time taken for the completion of 75% of a first-order reaction is not necessarily double the time taken for the completion of 50% of the reaction. The rate of a first-order reaction is dependent on the concentration of the reactant, not the percentage completion of the reaction.
