We’re being asked to determine the units for the rate of production of water for the reaction below:

2 NO + 2 H2 → N2 + 2 H2O

General or Average Rate is the change in the concentration of a compound over a period of time.

$\overline{){\mathbf{Rate}}{\mathbf{=}}\frac{\mathbf{\Delta }\mathbf{\left[}\mathbf{A}\mathbf{\right]}}{\mathbf{\Delta t}}}$

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
