Nitrogen and hydrogen gases are related in a 1:3 mole ratio at 700 K. Calculate the total pressure required to achieve 30% yield of ammonia at equilibrium given that the Kp for this ca
reaction at 700 K is 2.18 x 10-6 atm-2

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
