We’re being asked to calculate the rate for the formation of Cu(s).
Recall that the average rate of a reaction is given by:
Δ[A] = change in concentration of reactants or products (in mol/L or M)
Δtime = change in time.
What is the rate for the formation of Cu(s) in the reaction Cu2+(aq) + H2(g) ⇌ Cu(s) + 2 H+(aq) if Δ[H+] / Δt = 1.2 x 10 -3 ?
1. 6 x 10-4
2. 2.4 x 10-3
3. 1.2 x 10-3
4. 3 x 10-4
5. 2 x 10-4
