Five moles of calcium carbide is combined with 10 mol of liquid water in a closed, rigid, high-pressure vessel of 750-cm3 capacity. Acetylene gas is produced by the reaction:
![]()
Initial conditions are 298.15 K (25°C) and 1 bar, and the reaction goes to completion. For a final temperature of 398.15 K (12S0C), determine:
(a) The final pressure;
(b) The heat transferred. At 398.15 K (125"C), the molar volume of Ca(0H)2 is 33.0 cm3 mol-1. Ignore the effect of any gas present in the vessel initially.
