order

[Jesse Kuehn 1B]

how do we calculate or know what the reaction order is and what does the reaction order mean?

Hi! The reaction order is essentially the sum of all the exponents of the concentrations in the rate law.

[Jennifer Su 2L]

The order of a rate law is the sum of the exponents of its concentration terms. More specifically, the reaction order is the exponent to which the concentration of that species is raised, and it indicates to what extent the concentration of a species affects the rate of a reaction, as well as which species has the greatest effect. The order of the reactant (n) gives insight into the reaction mechanism.

using experimental data, as shown in lecture, we isolate changing concentrations of reactants by keeping the others constant and divide the rate and concentrations to obtain the order for that particular reactant. After doing so for each, we sum all of these orders to attain the overall reaction order.

Is it possible to know the order based on the balanced chemical equation? What other information would you need?

from what i recall i don't think we can if we are given a random equation as the coeffeicents don't always line up with the order of the reaction so the only sure way to figure it out is through experimental data
