Q76
Single choice
A researcher investigated the equilibrium between CO2, C, and CO as a function of temperature. The equation is given below:
CO2(g) + C(s) 2 CO(g)
Carbon dioxide, at 298 K and 1 atm, and an excess of powdered carbon were introduced into a furnace, which was then sealed so that pressure would increase as the temperature rose. The furnace was heated to, and held constant at, a predetermined temperature. The pressure within the furnace chamber was recorded after it had remained unchanged for one hour. The table below shows the pressures recorded for a series of temperatures together with the pressures expected if no reaction had taken place.
