A catalyst increases the rate of chemica...

A catalyst increases the rate of chemical reaction by providing an alternative reaction pathway which lowers the activation energy than the reaction pathway in its absence. A catalyst is not consumed and therefore does not appear in the chemical equation for the reaction. A homogenous catalyst is in the same phase as the ractants whilst a heterogeneous catalyst is in a different phase.
The complex `[Co(NH_(3))_(3)F]^(2+)+H_(2)Oto[Co(NH_(3))_(5)(H_(2)O+F^(-)]^(3+)`
and Rate `=k["complex"]^(a).[H^(+)]^(b)`
The reaction is acid catalysed , i.e. `[H^(+)]` does not change during the reaction . Thus, rate `=k'["complex"]` where, `k'=[H^(+)]^(b)`

From the above data, value of a is :

A

`1`

B

`2`

C

`0`

D

`(1)/(2)`
