Question

for the reaction
47kcal+2SO3(g)-2SO2(g)+O(g)
predict the effect on the position of equilibrium will it shift to the left or to the right or will there be no change for each of the following changes
the temperature is increased
the pressure is increased by decreasing the volume of the container

Answer 1

1)

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

Answer: Right

2)

We are decreasing volume here

In other words we are trying to increase pressure

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

Here reactant has less gaseous molecule

So equilibrium will move to left

Answer: Left
