1.

Following is the graph between `log T_(50)` and `log a` (`a =` initial concentration) for a given reaction at `27^(@)C`. Hence order is A. 1B. 2C. 3D. 0

Answer» Correct Answer - D
`t_(1//2)prop((1)/(a))^(n-1)" or "t_(1//2)=k(a)^(1-n)`
`logt_(1//2)=logk+(1-n)loga`
(It represents straight line equation, y = c + mx)
Slope `=(1-n)=tan45^(@)=1`
`(1-n)=1implies n=0`
