Rate constant k

Postby Stevin1H » Sun Mar 10, 2019 3:46 pm

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

k quantifies the rate at which the chemical reaction occurs and allows us to determine the overall rate using the formula given. We multiply k to the molar concentrations of the reactants to their order number to find Rate.

rate constant k determines how fast/slow the reaction occurs using the initial concentrations of the reactants

To add on, the rate constant, k, does have different units depending on what order the reaction is. The general rule is as follows for the units of k: 1/(Mn-1*t-1), where n is the order of the reaction.
