9.0 mol of pure ammonia gas was injected into a 3.0 L flask and allowed to reach equilibrium according to the equation 2 NH3(g) Û N2(g) + 3 H2(g). The equilibrium mixture was analyzed and found to contain 3.0 mol of hydrogen gas. Calculate the value of the equilibrium constant.

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l.s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?
