Consider the same reaction carried out two more times, both at the same condition(including concentration and temperature), but where the volume of the reaction is doubled in the second reaction. Since the concentrations are the same in both cases, the 2nd has twice the quantity of gases. How do those two rates of reaction compare to each other? Please compare using units of moles/(L•min) and separately using units of moles/min.
