What is the rate determining step in Cannizzaro's reaction?

Explanation

`H- overset(overset(O)(||))(C )-H+ OH^(-) rarr H-underset(underset(H)(|))overset(overset(O)(|))(C )-OH`

and `H-overset(overset(O)(||))(C )- OH + CH_(3)O^(-) rarr HCOO^(-) + CH_(2)OH`
Transfer of hydride ion on to the carbonyl carbon is the rate determining step in the Cannizzaro.s reaction
