For a first order reaction `t_(90%):t_(99%):t_(99.9%):t_(99.99%)=`

IF the t_(1//2) for a first order reaction 0.4 min, the time of or 99.9% completion of the reaction is ............min.

For a first- order reaction, the time required for 99.9% of the reaction to take place is nearly

Assertion : For a first order reaction, t_(1//2) is indepent of rate constant. Reason : For a first reaction t_(1//2) prop [R]_(0) .

For a first order reaction, show that the time required for 99% completion is twice the time required for the completion of 90% of reaction.

For a first order reaction, show that the time required for 99% completion is twice the time required for the completion of 90% of reaction.

For a first order reaction show that time required for 99% completion is twise the time required for the complation of 90% of reaction .

For a first order reaction, show that time required for 99% completion is twice the time required for the completion of 90% of reaction.

In the case of a first order reaction, the ratio of time required for 99.9% completion to 50% completion is
