" order required for the completion of "90%" of the reaction."

Prove that for a 1st order reaction, the time taken for 99% completion of the reaction is twice the time required for the completion of 90% of the reaction.

For a first order reaction the time required for 99% completion of the reaction is twice the time required for the completion of 90% of the reaction. Statement is True or false.
