Amixture of nh3(g) and n2h4(g) is placed in a sealed container at 320 k . the total pressure is 0.50 atm . the container is heated to 1200 k at which time both substances decompose completely according to the equations 2nh3(g)→n2(g)+3h2(g) ; n2h4(g)→n2(g)+2h2(g) . after decomposition is complete the total pressure at 1200 k is found to be 4.5 atm. part a find the percent (by volume) of n2h4(g) in the original mixture. (assume two significant figures for the temperature.)
