Solution: Solid carbon and gaseous carbon dioxide are placed in a closed vessel and allowed to come to equilibrium at a high temperature according to this equation.heat + C (s) + CO2 (g) ⇌ 2 CO (g)If the pressure on the system is increased and the temperature kept constant, what will be the result?a) The amount of CO will increase and that of C and CO 2 will decrease.b) The amount of CO will decrease and that of C and CO 2 will increase.c) The amount of each of the three subtances will increase.d) The amount of each of the three substances will decrease.
