Problem: Consider the following reaction: C4H8 (g) → 2 C2H4 (g) The following data were collected for the concentration of C4H8 as a function of time: A) What is the average rate of the reaction between 0 and 10s?B) What is the average rate of the reaction between 40 and 50s?C) What is the rate of formation of C2H4 between 20 and 30 s?

FREE Expert Solution

We’re being asked to calculate the average rate of the reaction for the following reaction:

C4H8 (g) → 2 C2H4 (g) 


Recall that for a reaction aA  bB, the rate of a reaction is given by:


Rate=-1aΔ[A]Δt=1bΔ[B]Δt


where: 

Δ[A] = change in concentration of reactants or products (in mol/L or M), [A]final – [A]initial

Δt = change in time, tfinal – tinitial
