🤓 Based on our data, we think this question is relevant for Professor Bindell's class at UCF.

Solution: Which of the following equilibria will shift to the left in response to a decrease in volume?a) H2 (g) + Cl2 (g) ⇌ 2 HCl (g)b) 2 SO3 (g) ⇌  2 SO2 (g) + O2 (g)c) N2 (g) + 3 H2 (g) ⇌ 2 NH3 (g)d) 4 Fe (s) + 3 O2 (g) ⇌  2 Fe2O3 (s)e) 2 HI (g) ⇌ H2 (g) + I2 (g) 

Problem

Which of the following equilibria will shift to the left in response to a decrease in volume?

a) H2 (g) + Cl2 (g) ⇌ 2 HCl (g)

b) 2 SO3 (g) ⇌  2 SO2 (g) + O2 (g)

c) N2 (g) + 3 H2 (g) ⇌ 2 NH3 (g)

d) 4 Fe (s) + 3 O2 (g) ⇌  2 Fe2O3 (s)

e) 2 HI (g) ⇌ H2 (g) + I2 (g)
