Question

Consider the following equilibrium: 2H_2(g) + X_2(g) rightarrow 2H_2X(g) Addition of X_2 to a system described by the above equilibrium a) will cause [H_2] to decrease b) will cause [X_2] to decrease c) will cause [H_2X] to decrease d) will have no effect e) cannot possibly be carried out Consider the following reaction: PCI_5(g) rightarrow PCl_3(g) + Cl_2(g) Which of the following will cause a shift in equilibrium to the right? a) add more PCl_5 b) remove Cl_2 c) remove PCl_3 d) all of the above e) cannot be determined

Explanation / Answer

6.

Adding a reactant shift the reaction in the direction of product

So more of H2 will be used up

Answer: a

7.
