Statement-1: The time of completion of reaction of type A->P (order<1) may be determined.
Statement-2: Reactions with order 1 are either too slow or too fast and hence the time of completion can not be determined.
Statement-1 is true, statement-2 is true and statement-2 is not the correct explanation for statement-1.
Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
Statement-1 is true, statement-2 is false
Statement-1 is false, statement-2 is true
The time of completion of the reaction of type (order<1) may be determined because for zero-order reaction there is a formula to calculate time of completion of the reaction.
Reactions with order 1 are either too slow or too fast and hence the time of completion can not be determined, it is false.
So, Statement-1 is true, statement-2 is false
Option 3 is correct.
