A student is studying a reaction between reactants A and B. the reaction is second order with respect to A, but zero order with respect to B. Explain in 5-6 sentences what this means.

If the Concetration of A is tripled what will the effect be on the reaction rate?

If the concentration of B is increased 10 times, what will the effect be on the reaction rate?

Solutions

Expert Solution

The order of a chemical reaction with respect to each reactant is defined as the exponent to which the concentration term of that reactant, in the rate law, is raised.

The reaction is second order with respect to A, but zero order with respect to B.

It means that in the rate law expression, the concentration of the reactant A is raised to the power 2 and the concentration of the reactant B is raised to the power 0. In other words, the rate law expression is

If the concentration of A is tripled, the reaction rate will increase 9 times.

If the concentration of B is increased 10 times, the reaction rate will remain unchanged.
