Which conclusion can be drawn if a graph is plotted between log `t_(50%)` vs. log [reactant] if it show an intercept 'A' and `tantheta=0`?

Options

A. `n=1, t_(1//2)=1/(K.a)`
B. `n=2, t_(1//2)=1/a`
C. `n=1, t_(1//2)=0.693/K`
D. None of these

Answer

c

Explanation

`t_(1//2)=K ["Reactant"]^(1-n)`
or `log t_(1//2)=log K+(1-n) log[R]`
`:' 1-n=0`
`:. n=1`
