Kinetics and Equilibrium Calculating equilibrium composition from an equilibrium constant Suppose a 250 mL flask is filled with 0.20 mol of I2 and 0.90 mol of HI. The following reaction becomes possible:
a) 3I2(g) + 2H2(g) ⇌ 2HI(g) + I3⁻aq
b) I2(g) + H2(g) ⇌ 2HI(g)
c) 2HI(g) ⇌ H2(g) + I2(g)
d) 2HI(g) + I2(g) ⇌ 3I2(g) + H2(g)"
