Rate Law

Front

What is the rate law for a reaction that is third order in A?

Back

Rate = k[A]^3

Front

What is the rate law for the reaction 2NO(g) + O2(g) → 2NO2(g) if it is first order in O2 and third order overall?

Back

Rate = k [NO]^2[O2]^1

Front

Determine the order of F2 and ClO2 if both are first order.

Back

(F2 - 1st order) (ClO2 - 1st order)

Front

What is a possible rate law for a reaction that is third overall order?

Back

Rate = k [A]^2[B]

Front

What is the rate exponent for A if the rate law shows no dependence on A?

Back

0

Front

Define 'rate law' in the context of chemical reactions.

Back

The rate law is an equation that relates the rate of a reaction to the concentration of its reactants.

Front

What does a first order reaction imply about the concentration of reactants?

Back

The rate of reaction is directly proportional to the concentration of one reactant.

Front

How do you determine the overall order of a reaction?

Back

By summing the exponents of the concentration terms in the rate law.

Front

What is the significance of the rate constant (k) in a rate law?

Back

The rate constant (k) is a proportionality factor that is specific to a given reaction at a specific temperature.

Front

What does it mean if a reaction is zero order with respect to a reactant?

Back

The rate of reaction is independent of the concentration of that reactant.
