Question

For the reversible reaction by pcl5(g) + heat pcl3(g) + cl2(g) the equilibrium shifts in forward direction by

Answer 1

Answer:

by increasing the reactants the equilibrium will shift in forward direction and by decreasing the pressure the same result is found

Answer 2

For the reversible reaction,

PCl5 + heat---------> PCl3 + Cl2

the equilibrium will shift in a forward direction in the following conditions:

1. Increase in concentration of reactants. As the concentration of reactants increases the reaction will try to stabilise the equilibrium. So, it will shift in the forward direction.
2. Decrease in concentration of products. As the product concentration decreases to maintain the equilibrium the reaction will shift itself in a forward direction and form the product.
3. Increasing the Volume. As the volume increases the reaction travels in a direction where the number of moles is more. In our case, the reaction will travel in forward direction.
