In the reaction alternative. `2Hl(g)toH_(2)(g)+l_(2)(g)` Choose the correct alternative.A. Rate of reaction `=(1)/(2)(Delta[HI])/(Deltat)=(Delta[H_(2)])/(Deltat)=(Delta[I_(2)])/(Deltat)`B. Stoichiometric coefficients of HI (reactant ) and `H_(2) and l_(2)` (products) are not same.C. Rate of consumption of HI=2 (rate of formation of `H_(2) Or l_(2))`D. All of the above

Answer» Correct Answer - D
For the given reaction ,
`2HI(g)to H_(2)(g)+I_(2)(g)`
`(dx)/(dt)=(1)/(2)(d[HI])/(dt)=+(d[H_(2)])/(dt)=+(d[I_(2)])/(dt)`
Stoichiometric coefficient (HI) `ne` Stoichiometric coefficient
`H_(2) or I_(2)`
Rate of consumption of HI=2 (rate of formation of ` H_(2) or I_(2)`
Hence, all the statements are true.
