In the reaction given below,
   $2\mathrm{HI}\left(\mathrm{g}\right)⟶{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{I}}_2\left(\mathrm{g}\right)$
Choose the correct alternative.

Rate of reaction$=-\frac{1}{2}\frac{\mathrm{\Delta }\left[\mathrm{HI}\right]}{\mathrm{\Delta t}}=\frac{\mathrm{\Delta }\left[{\mathrm{H}}_2\right]}{\mathrm{\Delta t}}=\frac{\mathrm{\Delta }\left[{\mathrm{I}}_2\right]}{\mathrm{\Delta t}}$

Rate of consumption of HI = 2 (rate of formation of H₂ or I₂)

All of the above statements are true

Stoichiometric coefficients of HI (reactant) and H₂ and I₂ (products) are not same
