AH" 180.8 kJ, In what direction will the reaction move to reestablish equilibrium ifthe temperature is decreased? (reactants, products, or no change) Numerical Value of K 4. For the reaction: Aunt Baal 2AB(g), the concentration-time graph is as follows: What is the value of the equilibrium constant? 86% a

Explanation / Answer

Ans 1 - The no of moles of left hand side are 4 and on right hand side are 2

The increase in volume will cause the shift in equilibrium on the side with more moles.

So due to this reason the equilibrium will shift to left as left hand side of reaction has more moles in comparision to right hand side (4 in left hand side and 2 on right hand side).
