b) What are the units of Kc?
c) What is the value of Kc for the reverse reaction at 200 ° C and what are its units?
d) How would it affect the value of Kc if:
i.add PCl5
ii.pressure increases
iii.the temperature rises.
e) A sample of pure PCl5 was placed in an empty container at 200 ° C. When equilibrium was reached, the concentration of PCl5 was 0.5 × 10 ¹. What are the concentrations of PCl3 and Cl2 in equilibrium?
