Question

You are given a set of experimental data for a chemical reaction, including the concentrations of reactants and products at different times. Determine the order of the reaction and the rate constant.

• A. First order, rate constant = 0.5
• B. Second order, rate constant = 1.2
• C. First order, rate constant = 1.5
• D. Zero order, rate constant = 0.8

Hint:

Use integrated rate laws to determine the order of a reaction by comparing how concentration changes over time.

Answer 1

The Correct Option is C

To determine the order of the reaction and the rate constant, you would analyze the experimental data and use the integrated rate laws for different orders (zero, first, second). For a first-order reaction, the concentration of reactants decreases exponentially over time. From the given data, we would calculate the rate constant and identify the reaction order based on the best fit to the experimental data.
