Ethylene is the starting point for a wide array of industrial chemical syntheses. For example, worldwide about 8.0 x 10^10 of polyethylene are made from ethylene each year, for use in everything from household plumbing to artificial joints. Natural sources of ethylene are entirely inadequate to meet world demand, so ethane from natural gas is "cracked" in refineries at high temperature in a kinetically complex reaction that produces ethylene gas and hydrogen gas. Suppose an engineer studying ethane cracking fills a 50.0 L reaction tank with 12.0 atm of ethane gas and raises the temperature to 800. C. He believes Kp= .090 at this temperature. Calculate the percent by mass of ethylene the engineer expects to find in the equilibrium gas mixture. Round your answer to significant digits.
