A chemical engineer is studying the following reaction: 2 NO(9)+2H,(9) - N(9)+2H,0(9) At the temperature the engineer picks, the equilibrium constant K, for this reaction is 3.6. The engineer charges ("fils") four reaction vessels with nitrogen monoxide and hydrogen, and lets the reaction begin. He then measures the composition of the mixture inside each vessel from time to time. His first set of measurements are shown in the table below. Predict the changes in the compositions the engineer should expect next time he measures the compositions. reaction vessel compound pressure expected change in pressure NO 3.77 atm Of increase OI decrease O (no change) 2.70 stm O f nerease O I decrease O (no change) 9.15 atm Ot norease OI decrease O (ne change) 3.00 atm Of nerease OI decrease O (ne change) NO 245 stm Of increase OI decrease O(me change) 3 stm Of inerease 0 decrease O (na change) N 931 atim Of inerease Oi decrease 25onge) H,0 432 tm 1 norease Oi decrease O (no change) NO 365atm Ot nerease Oi decrease O (he change) 258 atm O norease O decrease O (no change) anlanatin Check
