A gaseous mixture containing 0.150 mol fraction of carbon tetrachloride (CCl4) and 0.850 mol fraction of dry air is initially at 65.0°C and 1121 mmHg. If this mixture is cooled at a constant pressure
1. at what temperature does the CCl4 first start to condense?
2. At what temperature would 30.0% of the CCl4 condense?
