Question

Can somone pls tell me what the trem ao represents here(when a is the initial concentration)?Q.NO.1

Answer 1

it is the final concentration

Answer 2

Hello again
It is a^0.=1
For first order reaction t½ is independent of the initial concentration a.As the t½ of first order reaction is 0.693/k where k is rate constant.
The correct answer is (2)
Because t½ of zero order reaction is a/2k so it is directly proportional to concentration a whereas for first order reaction t½ is independent of initial concentration as discussed earlier.
All the best!
