Question

E178.1(b) In a study of the enzyme-catalysed oxidation of ethanol, the molar concentration of ethanol decreased in a first-order reaction from 220 mmol dm$^{-3}$ to 56.0 mmol dm$^{-3}$ in 1.22 x $10^4$s. What is the rate constant of the reaction?

Step 1

Step 1: For a first-order reaction, the integrated rate law is given by: $$ln([A]_t) - ln([A]_0) = -kt$$ where: $[A]_t$ is the concentration at time t $[A]_0$ is the initial concentration k is the rate constant t is the time Show more…
