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.

FREE Expert 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:


<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>xA</mi><mo>&#x2192;</mo><mi>yB</mi></math>


The rate of reaction (in terms of A and B) is expressed as:
