Use the van der Waals equation of state to calculate the pressure P of 3.50 mol of Xe at 469 K in a 5.50 L vessel. Use this list of van der Waals constants. P = atm Use the ideal gas equation to calculate the pressure P under the same conditions. P = atm

A chemical engineer is studying the following reaction: HCN(aq) + NH3(aq) → CN¯(aq)+NH(aq) At the temperature the engineer picks, the equilibrium constant K for this reaction is 0.70. C The engineer charges ("fills") four reaction vessels with hydrogen cyanide and ammonia, and lets the reaction begin. She then measures the composition of the mixture inside each vessel from time to time. Her first set of measurements are shown in the table below. Predict the changes in the compositions the engineer should expect next time she measures the compositions. reaction vessel compound concentration expected change in concentration HCN 0.59 M ↓ decrease (no change) NH₂ 0.73 M ↓ decrease (no change) A CN 0.56 M (no change) NHA 0.54 M ↓ decrease decrease ↓decrease (no change) HCN 0.21 M (no change) NH3 0.35 M ↓ decrease (no change) B CN 0.94 M NH 0.92 M ↓ decrease ↓decrease ↓decrease (no change) (no change) (no change) HCN 0.32 M NH3 0.46 M ↓decrease (no change) ↑ increase ↑ increase ↑ increase ↑…
