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?
Does the reaction occur spontaneously at the temperature of 298 K and standard state conditions also Calculate the value of S°univ.
If the pressure increases to 800. torr, how many moles of gas were added to the container? Assume a constant-volume container.
For each of the following processes, decide whether it is spontaneous or non-spontaneous.
When heat is added to a solution of CoCl2 and HCl in water, what happens on the molecular level that causes the reaction to shift?
A steel cylinder with nitrogen, hydrogen, and ammonia gases is at 500°C and 4.91 atm. If the partial pressure of nitrogen is 1850 mmHg and hydrogen is 1150 mmHg
