The reaction C(s) + CO₂ (g) 2 CO (g) reduces CO₂ (carbon dioxide) to CO (carbon monoxide). A container holds an equilibrium mixture of solid carbon (C) and gaseous CO₂ and CO. The initial amount of C(s) present is 2 g. We now add more CO₂ to the mixture (while keeping the temperature and volume occupied by the gases the same). Once equilibrium is re-established the mass of C(s) present will be [blank] 2 g.

A. greater than

B. less than

C. equal to
