Chemical Kinetics

Question

Wired Faculty App

Express the rate of the following reaction in terms of disappearance of the reactants and appearance of products:
H₂(g) + l₂(g) → 2HI(g)

Solution

The rate of reaction in terms of disappearance of the reactant and appearance of product.

H₂(g) + l₂(g) → 2HI(g)

$rate = \frac{- d [H_{2}]}{dt} = \frac{- d [I_{2}]}{dt} = \frac{1}{2} \frac{d (HI)}{dt}$
