Solution: Consider the following reaction: 2 HBr(g) → H2(g) + Br2(g)Express the rate of the reaction in terms of the change in concentration of each of the reactants and products.

Solution: Consider the following reaction: 2 HBr(g) → H2(g) + Br2(g)Express the rate of the reaction in terms of the change in concentration of each of the reactants and products.

Problem

Consider the following reaction: 2 HBr(g) → H2(g) + Br2(g)

Express the rate of the reaction in terms of the change in concentration of each of the reactants and products.

Solution

The rate of a chemical reaction is the speed at which the reactants are converted into products.


It is expressed as the change in concentrations of reactants or products over time.


For a hypothetical reaction:
