In a 3.0-L vessel, the following equilibrium partial pressures are measured: N2, 190 torr; H2, 317 torr; NH3,
(a) How will the partial pressures of H2, N2, and NH3 change if H2 is removed from the system? Will they increase, decrease, or remain the same?
(b) Hydrogen is removed from the vessel until the partial pressure of nitrogen, at equilibrium, is 250 torr. Calculate the partial pressures of the other substances under the new conditions.

- 2SO2(g)+O2(g)⇄2SO3(g)Kp≈2×105At a certain temperature, SO2(g) and O2(g) react to produce SO3(g) according to the chemical equation shown above. An evacuated rigid vessel is originally filled with SO2(g) and O2(g), each with a partial pressure of 1atm. Which of the following is closest to the partial pressure of O2(g) after the system has reached equilibrium, and why?a) 0atm; because Kp is very large, nearly all the SO2(g)and O2(g) are consumed before the system reaches equilibrium.b) 0.5atm; because Kp is very large, nearly all the SO2(g) is consumed before the system reaches equilibrium, but an excess amount of O2(g) remains at equilibrium.c) 1atm; because Kp is very large, the system is already near equilibrium, and there will be very little change to the partial pressure of O2(g).d) 1.5atm; because Kp is very large, the decomposition of any SO3(g) that forms increases the amount of O2(g) at equilibrium.arrow_forwardWhat will happen to the equilibrium when the pressure of the system is increased? 2SO2(g) + O2(g) ⇌ 2SO3(g)arrow_forwardConsider the equilibriumN2O4(g) ⇌ 2 NO2(g) ΔH° = 58.0 kJIn which direction will the equilibrium shift when (a) N2O4 is added, (b) NO2 is removed, (c) the pressure is increased by additionof N2(g), (d) the volume is increased, (e) the temperature is decreased?arrow_forward
