🤓 Based on our data, we think this question is relevant for Professor Young's class at ST THOMAS.
We’re being asked to calculate the average rate of the reaction for the following reaction:
2 FeCl3(s) → 2 Fe(s) + 3 Cl2(g)
For the reaction, the concentration FeCl3 changes from 1.000 M to 0.444 M in the first 10 seconds.
Recall that for a reaction aA → bB, the rate of a reaction is given by:
Δ[A] = change in concentration of reactants or products (in mol/L or M), [A]final – [A]initial
Δt = change in time, tfinal – tinitial
For the reaction given, the FeCl3 changes from 1.000 M to 0.444 M in the first 10 seconds.
Calculate the average rate in the first 10 seconds.
2 FeCl3 (s) → 2 Fe (s) + 3 Cl2 (g)
a. 0.0384 M/s
b. 0.210 M/s
c. 0.0278 M/s
d. 0.0874 M/s
e. 0.568 M/s
