Methane reacts with I2 as per to the reaction CH4 (g)+ I2 (g) in equilibrium with CH3I (g) + HI (g). At 630 K, Kp for this reaction is 2.26 x 10(-4). If a reaction was set up at 630K with initial partial pressures of methane of 105.1 torr and of 7.96 torr for I2. Compute the pressures, in torr, of all reactants as well as products at equilibrium.
