Consider the reaction, $2 \mathrm{C}(\mathrm{s})+\mathrm{O}_{2}(\mathrm{g}) \rightleftharpoons 2 \mathrm{CO}(\mathrm{g})$ at equilibrium, The equilibrium can be shifted towards the forward direction by
(a)Increasing the amount of carbon in the system
(b)Decreasing the volume of the system
(c)Decreasing the pressure of the system
(d)Increasing the temperature of the system
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
2C(s) + O₂ → 2CO increases gas moles; lowering the pressure shifts it forward (c); solid C does not affect the equilibrium and the reaction is exothermic.
