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.

I believe the complete
given is that the bucket of sand contains 9.5 billion grains of sand. That is:
bucket = 9,500,000,000
grains
and the concentration of
brown sand is 2 ppm:
concentration brown sand =
2 / 1,000,000
Therefore:
brown sand = 9,500,000,000
* (2 / 1,000,000)
<span>brown sand = 19,000 grains</span>
Answer:
THE CORRECT ANSWER IS COMMAND.HOPE IT HELP YOU
