Rate of Chemical ReactionChemical Kinetics

For the reaction 2HI(g)→H2(g)+I2(g)2HI(g) \rightarrow H_2(g) + I_2(g) , express the rate of reaction in terms of the disappearance of HI.

Expert Answer

Rate=−12Δ[HI]Δt\text{Rate} = -\frac{1}{2}\frac{\Delta[HI]}{\Delta t} (Stoichiometric coefficient divides the rate of change).
