# Problem: 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 10-42. 2.4 x 10-33. 1.2 x 10-34. 3 x 10-45. 2 x 10-4

###### FREE Expert Solution

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:

$\overline{){\mathbf{Rate}}{\mathbf{=}}\frac{\mathbf{∆}\left[A\right]}{\mathbf{∆}\mathbf{time}}}$

where:
Δ[A] = change in concentration of reactants or products (in mol/L or M)
Δtime = change in time
