Question

When the chemical reaction shown below is at equilibrium, if the volume is reduced, in what direction would the reaction shift? C3H8(g) + 5 O2(g) ⇌ 3 CO2(g) + 4 H2O(l) ΔH° = −2220 kJ

a. To the left

b. To the right

c. No change

Would it shift to the left? Or right since volume works inversely of pressure

Answer 1

Decreasing volume will increase the pressure which in turn shift the reaction in a direction which have lesser gaseous molecules as per Le chatelier Principle

Here product has less gaseous molecule

So equilibrium will move to right

So, Equilibrium moves to product side

Answer: b
