Question

The reaction A + 2B + C --> Products has a rare law of Rate = k[A]^2[B]. By what factor would the reaction rate change if [B] is tripled? 

Expert Solution
Step 1

The order of a chemical reaction can be determined by measuring the rate of reaction at different initial concentrations of the reactants.

  • If we doubled the initial concentration of the reactants and the rate of reaction remains constant, then the order of the reaction with respect to that reactant is one (first-order reaction).
  • If we doubled the initial concentration of the reactants and the rate of reaction is also doubled the order of the reaction with respect to that reactant is one (first-order reaction).
  • If we doubled the initial concentration of the reactants and the rate of reaction is increased by four times the order of the reaction with respect to that reactant is two (second-order reaction).
