Cyclopropane is converted to propene in a first-order process. The rate constant is 5.4 × 10⁻² hr⁻¹. If the initial concentration of cyclopropane is 0.150 M, what will its concentration be after 22.0 hours?

Question

Quizplus · Accepted Answer

The concentration of cyclopropane after 22.0 hours can be calculated using the first-order kinetics formula: [A] = [A]₀e^(-kt). Substituting the given values: [A] = 0.150e^(-5.4 × 10^−2 × 22.0) = 0.0457 M.
