Answer:
a) the reverse reaction is favoured
b) the forward reaction is favoured
c) the forward reaction is favoured
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.
Answer:
its the 3rd option.
the molecules move from region of higher concentration to a region of lower concentration.

thank you and have a great day :D
Answer:
a) 37.04% b) 37.04% c) 9.63%
Explanation:
The theoretical percent recovery (Tr), is the total percentage of each compound in the sample. Depending on the technique used to recovery the compounds, the percent recovery will be less than the theoretical, because no technique is 100% efficient.
So, to calculate the theoretical, it will be the mass of the compound divided by the mass of the sample multiplied by 100%.
a) Tr = (250 mg)/(675 mg) * 100%
Tr = 37.04%
b) Tr = (250 mg)/(675 mg) * 100%
Tr = 37.04%
c) Tr = (65 mg)/(675 mg) * 100%
Tr = 9.63%
