For the reaction: `aA + bB rarr cC+dD`
Rate `= (dx)/(dt) = (-1)/(a)(d[A])/(dt) = (-1)/(b)(d[B])/(dt) = (1)/( c)(d[C])/(dt) = (1)/(d)(d[D])/(dt)`
A reaction follows the given concentration-time graph. The rate for this reaction at `20 s` will be

A

`4 xx 10^(-3) M s^(-1)`

B

`1 xx 10^(-2) M s^(-1)`

C

`2 xx 10^(-2) M s^(-1)`

D

`7 xx 10^(-3) M s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
If `H_(2)O` is in excess, the order of the reaction will be `1`.
