5. Suggest 5 ways that the concentration of PH3 couldbe increased in the following reaction.
P4 (g) + 6 H2 (g) ⇌ 4 PH3 (g)       ΔHo = 110kJ/mol
6. Gaseous nitrogen dioxide forms gaseous dinitrogen tetroxidewith a keq = 164 at 25°C in a 2.00L container
           a. Write and balance the equation
b. If at a giventimepoint the concentrations of nitrogen dioxide was measured to be0.500 M and the concentration of dinitrogen tetroxide was measuredto be 1.25 M, is the reaction at equilibrium?
           c. What are the concentrations at equilibrium?
d. After the initialequilibrium, if 5.00mol of dinitrogen tetroxide was introduced intothe container, what are the concentrations of both species whenequilibrium reestablishes?
