Rate of reaction is the change in concentration of any one of the reactants or any one of the products in unit time
(i) Express the rate of the following reaction in terms of reactants and products :
`2" HI" to H_(2)+I_(2)`
(ii) If the expression for the above reaction is, rate `=k[HI]^(2)`, what is the order of the reaction.
(iii) Are the order and molecularity of the above reaction same ? Give reason.

Text Solution

Verified by Experts

`[(i)-(1)/(2)(d[HI])/(dt)=(d[H_(2)])/(dt)=(d[I_(2)])/(dt)(ii)" 2 "]`
