Rate constant k

Postby Stevin1H » Sun Mar 10, 2019 3:48 pm

What is the conceptual idea for rate constant k in the equation? What does the rate constant k mean for the reaction?

The rate constant is a coefficient of proportionality relating the rate of a chemical reaction at a given temperature to the concentration of reactants.

Think of it as the rate that the chemical reaction is going, in terms of time.

k is used to symbolize the rate the chemical reaction is going related to the concentration of reactants and products.

Every reaction has a unique k. Also, you should know how to find the units of k based on the fact that rate = M/s.

The rate constant is equal to the rate of a reaction at the singles concentration of the reactants.K depends on the nature of the reactant, temperature, and the presence of catalyst.
