A container with volume 1.78 L is initially evacuated. Then it is filled with 0.246 g of N2. Assume that the pressure of the gas is low enough for the gas to obey the ideal-gas law to a high degree of accuracy. Part AIf the root-mean-square speed of the gas molecules is 192 m/s, what is the pressure of the gas?

1. A sample of solid ammonium chloride was placed in an evacuated container and then heated so that it decomposed to ammonia gas and hydrogen chloride gas. After heating, the partial pressure of NH3 in the container was found to be 2.2 atm. Calculate Kp at this temperature for the decomposition reaction: NH4Cl (s) ⇄ NH3 (g) + HCl (g). 2. Consider the endothermic reaction Fe3+ (aq) + Cl¯ (aq) ⇄ FeCl2+ (aq). Use Le Châtelier’s principle to predict how...
