Question
In our chem lab chlorine gas can be bubbled through water to form hydrogen chloride gas and
molecular oxygen . In certain temperatures a reaction system containing all species has been
allowed to come to equilibrium and the partial pressures of each of the compounds are: Pa2 =
0.300 atm, PHCI = 1.42 atm, and Po2 = 2.55 atm. Another system contains the same reactants
and products at the following pressures: Paz = 0.350 atm, PHCI = 2.15 atm, and Po2 = 4.35 atm. Is
this second system at equilibrium? If not, how will the reaction shift to reach equilibrium?
2 H20(1) + 2 Cl2(g)=4 HCI(g) + O2(g)

Expert Solution
Step 1

The reaction taking place is given as,

Chemistry homework question answer, step 1, image 1

Given : First system is in equilibrium with partial pressure of gases as,

=> PO2 = 2.55 atm 

=> PHCl = 1.42 atm

And PCl2 = 0.300 atm
