Question

The decomposition of in solution in carbon tetrachloride is a first-order reaction: The rate constant at a given temperature is found to be . If the initial concentration of is 0.200 M, what is its concentration after exactly 10 minutes have passed?

Answer 1

see below

Step-by-step explanation:

The rate constant is missing in question, but use C(final) = C(initial)e^-kt = 0.200M(e^-k·10). Fill in k and compute => remaining concentration of reactant

Answer 2

C(initial)e^-kt = 0.200M(e^-k·10).

Step-by-step explanation:

The rate constant is missing in question, but use C(final) = C(initial)e^-kt = 0.200M(e^-k·10).

Fill in k and compute => remaining concentration of reactant
