(a) Explain why `H_(2)and O_(2)` do not react at room temperature.
(b) Writen the rate equation for the reaction
`A_(2)+3B_(2)to 2C,` if the overall order of the reaction is zero.

Explanation

(a) `H_(2)and O_(2)` do not react at room temperature because the activation energy is high for that reaction which is not provided at room temperature.
(b) For zero order reaction : `" "Rate=k[A_(2)]^(@)[B_(2)]^(@)`
