Orders of reactants

Postby IreneSeo3F » Sun Mar 07, 2021 11:40 pm

What does the orders of the reactants inform us about the reaction? What is its significance?

The order of the reactant tells us how the reactant affects the reaction rate. This is significant because we can understand if a reactant is contributing to the speed of the reaction or if it is not.

To add on, the rate of the reaction A + B + C -> P is equal to k[A]^N [B]^M [C]^L. N, M, and L are the orders of the reactants, so you can see how increasing/decreasing them would affect the reaction rate. Hope that helps!

The order of the reactants tell us how significant that reactant is in contributing to the reaction rate. It gives an idea about how the reactants react with each other and also an idea of the steps of the reaction.

It tells us how the reactant affects the reaction rate. Different orders have different equations that are equal to the slope which is the reaction rate.

The order tells us how much each reactant affects the rate of the reaction. So a second order reactant would have more of an effect than a first order reactant. A zero order reactant has no effect on the rate.

Order tells you how much the concentration of a species affects the reaction rate. For example, with the reaction A + 3B + 2C --> products, the rate law is given by rate = k[A][B]^2. Overall, the reaction is third-order, with first-order in A, second-order in B, and zero-order in C. Since C is zero-order, this means that the concentration of C doesn't affect the rate. However, C must still be present to let the equilibrium mixture form.

I agree with the previous posts! The order of the reaction tells us how the reactants will affect the rate. As the order increases, the reactants will have a higher effect. Zero order has no effect and second order has the most. Hope this helps!

The order of the reactant indicates the magnitude of the effects of changing the concentration of a reactant on the rate of the reaction.

The reaction order also tells us what units we will expect for k as well as how much the rate will change when the concentration of one of the products is changed.

Order of the reaction ties the change in rate to the change in initial concentration

The order of each reactant tells us the relationship between the concentration of the reactant and the rate of the reaction. Additionally, it provides insight into the reaction mechanisms (lecture 24).

The order of reactants shows you how the reactant concentration affects the reaction rate.

The reaction sequence also informs us what units to expect for k and how much the rate will change when one of the products' concentrations is modified.

The orders of the reactants inform us on how each reactant effects the overall rate of reaction.
