WORK!!!!
Create an ICE TABLE for all of the following AND SHOW YOUR WORK!!!!
1.
A student ran the following reaction in the laboratory at 425 K:
PCl5(g)
PCl3(g) + Cl2(g)
When she introduced 3.38 moles of PCl5(g) into a 1.00 liter container, she found the equilibrium concentration
of Cl2(g) to be 3.38×10-2 M.
