Equilibrium questions

Can someone help me with this
How to solve this type of problem


Hope this helps you:)


great method
and how to concentration of A, B and C at equilibrium

It was asking about the moles not the concentration.
You shouldn’t pay attention to the volume here. It’s actually useless.

Yeah but I was asking about second question, like how you calculate concentration here and volume is 2.00 dm^3

You just need to divide each mole by the volume of the mixture and then the concentration will be reached!
