For the equilibrium H2(g) + I2(g) ? 2HI(g), which change will decrease the equilibrium concentration of HI?
For the gas equilibrium CO(g) + 2H2(g) ? CH3OH(g), what is the effect of increasing total pressure (by decreasing volume) on the position of equilibrium?
For the equilibrium A(g) ? B(g) + C(g), which operation will change the equilibrium constant K?
