Question

What effect does a. Increasing the total pressure and b. Increasing the temperature have on the equilibrium H2+CO2 5. What effect does a) increasing the total pressure and b) increasing the temperature have on the equilibrium H2(g) + CO2(g) H2O(g) + C0(g), AF1° = 41.2 kJ/mol. a. a) equilibrium shifts towards products, b. a) equilibrium shifts towards reactants, c. a) equilibrium shifts towards products, d. a) no change in the equilibrium, e. a) no change in the equilibrium, b) equilibrium shifts towards products. b) equilibrium shifts towards products. b) equilibrium shifts towards reactants. b) equilibrium shifts towards products. b) equilibrium shifts towards reactants.

Explanation / Answer

Effect of increasing pressure:

We are increasing pressure here

so, according to Le Chatelier's principle,

Reaction will try to decrease the pressure

Hence it will move in a direction which have lesser gaseous molecules

But number of gas is same on both sides.

So, there will not be any effect on equilibrium

Effect of increasing temperature:

Forward reaction is endothermic in nature

we are increasing temperature or adding heat here

so, according to Le Chatelier's principle,

equilibrium will move in direction which absorbs heat

hence, forward reaction will be favoured

Equilibrium moves to product side

Answer: d
