Final answer:
To determine the average rate of dimerization, use the change in concentration of C₄H6 over a given time period. To estimate the instantaneous rate, calculate the slope of the line tangent to the graph at a specific time. Units of the instantaneous rate are M/s.
Step-by-step explanation:
To determine the average rate of dimerization between 0s and 1600 s, we need to calculate the change in concentration of C₄H6 during that time period. Let's assume the initial concentration of C₄H6 is A₀ and the final concentration at 1600 s is A₁. The average rate of dimerization is given by the formula:
Average rate = (A₁ - A₀) / (time)
Similarly, to determine the average rate of dimerization between 1600 s and 3200 s, we need to calculate the change in concentration of C₄H6 during that time period. Let's assume the concentration at 1600 s is B₀ and the concentration at 3200 s is B₁. The average rate of dimerization is given by the formula:
Average rate = (B₁ - B₀) / (time)
To estimate the instantaneous rate of dimerization at 3200 s from a graph of time versus [C₄H6], we need to calculate the slope of the line tangent to the graph at 3200 s. The units of this rate would be M/s.
