A chemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: 2NO(g) +  Cl2(g)⇌ 2NOCl(g) Kp=2.x10^−1   He fills a reaction vessel at this temperature with 10.atm of nitrogen monoxide gas and 12.atm of chlorine gas. Use this data to answer the questions in the table below. Can you predict the equilibrium pressure of NOCl, yes or no? If yes, then what is the equilibrium pressure of NOCl? Round your answer to 1 significant digit.
