A gaseous mixture containing 0.220 mol fraction of carbon tetrachloride (CCl4) and 0.780 mol fraction of dry air is initially at 60.0°C and 1127 mmHg.
1. If this mixture is cooled at a constant pressure, at what temperature does the CCl4 first start to condense?
2. At what temperature would 38.0% of the CCl4 condense?
