For a first order reaction A rarr product with initial concentration x " mol L'^(-1) m has a half life period of 2.5 hours. For the same reaction with initial concentration . (x/2) " mol L"^(-1) the half life is ......

Answer»

`(2.5xx2)` hours
`((2.5)/2)` hours
2.5 hours
Without knowing the rate constant , `t_(1//2)` cannot be determined from the given data

SOLUTION :For a FIRST order reaction
`t_(1//2) = (0.693)/K`
`t_(1//2)` does not depend on the initial concentration and it remains constant (WHATEVER may be the initial concentration )
