KP = 1.000 x 10–4 for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g). The reaction is at equilibrium when PH2 = 4.00 atm, PN2 = 4.00 atm, and PNH3 = 0.16 atm.
a) Show that these are equilibrium concentrations.
b) If the pressure of the system is doubled (the pressure of each gas doubles), what is the final pressure of each gas when equilibrium is restored?
If making and using ammonia is important to feeding the world's growing population but is causing serious environmental damage, should we stop making ammonia?
