A 25 C the vapor pressure of n-pentane (C5H12) is 511 torr and the vapor pressure of n-hexane (C6H14) is 145 torr. If a solution is made from 100 g of pentane and 100 g of hexane, what will be the mole fraction of pentane in the gas phase over that solution (if only hexane and pentane vapor are present)? Assume no deviation from Raoult's law
Consider the following reversible reaction. In a 1-liter container the following amounts are found in euilibrium at 400 deg C., 0.0536 mole N2, 0.599 mole H2, and 0.0437 mole NH3. Evaluate Kc = N2(g) + 3 H2(g)-> 2 NH3(g) answer in significant figu..
