Question

Question 10 1 pts Consider the equilibrium: CH, (g) + H2O(g) + 206 kJ CO(g) + 3H2(g). Which of the following disturbances will NOT cause the system to shift to the right to reestablish equilibrium? The volume decreases. The temperature increases. The partial pressure of CO decreases. All of these will cause the system to shift to the right. • The partial pressure of CH4 increases.

Answer 1

Option 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 reactant has less gaseous molecule

So equilibrium will move to left

So, Equilibrium moves to reactant side

Option 2)

Increasing Temperature will shift the reaction in a direction which absorbs heat as per Le chatelier Principle

Forward reaction is endothermic in nature

hence, forward reaction will be favoured

So, Equilibrium moves to product side

Option 3)

Removing product will shift the reaction in the direction of product as per Le chatelier Principle

So, Equilibrium moves to product side

Option 5)

Adding reactant will shift the reaction in the direction of product as per Le chatelier Principle

So, Equilibrium moves to product side
