Answer:

a) the reverse reaction is favoured

b) the forward reaction is favoured

c) the forward reaction is favoured

Step-by-step explanation:

The equation ought to have been correctly written as;

3A + 2B --------> C + 2D. ∆H =20 kJ

Actually, we can see that the reaction is endothermic since ∆H= positive.

We know that when pressure is decreased, the reaction tends towards the side with higher total volumes. There are five volumes(moles) of reactants and three volumes(moles) of products. A decrease in pressure will favour the reverse reaction.

Being an endothermic reaction, increase in temperature is known to favour the forward reaction. Similarly, removing D will drive the equilibrium forward thereby favouring the forward reaction.
