Question

Compounds A and B react to give a single product, C. Write the rate law for each of the following cases and determine the units of the rate constant by using the units M for concentration and s for time:

Answer 1

Answer:

Explanation:

Rate laws are mathematical expressions which define the relationship that exists between the rate of a chemical reaction and the concentration of the reacting components. Rate laws take the following form:

$rate = k [A]^{x} [B]^{y} [C]^{z}$...

where k = rate constant

[A], [C] and [C] represent the molar concentrations of the reactants

k, x, y, and z are determined experimentally by observing how the rate of reaction changes with the concentrations of the reactants.

If x=1, the reaction is first order for [A]. Also, if y=2, the reaction is second order for [B] and so on...

The overall order of the reaction is the sum of the orders with respect to each reactant. Therefore, the overall order of the reaction is x+y+z.
