Question

24-25. Consider the following equilibrium: 2H2(g) + X2(g) 2H2x(g) + energy 24. What will happen if we increase the temperature to the above equilibrium? A) B) C) D) will cause [H2X] to increase. will cause [X2] to decrease. will cause [H2X] to decrease. will have no effect. 25. Increasing the pressure by decreasing the volume will cause A) the reaction to occur to produce HzX. B) the reaction to occur to produce H2 and X. C) t D) no reaction to occur. he reaction to occur to produce H2 but no more X

Explanation / Answer

24)
1)
Increasing Temperature will shift the reaction in a direction which absorbs heat as per Le chatelier Principle
Forward reaction is exothermic in nature
hence, backward reaction will be favoured
So, Equilibrium moves to reactant side
Answer: C

2)
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: A
