Document Summary

1 n2o3 (g) decomposes to no (g) and no2(g) with a h0 = 40. 5 kj mol-1 according to the equilibrium: Circle the correct answer (a) more h2o3 (g) is added, volume stays fixed: Shift right stay the same (b) more no2 (g) is added, volume stays fixed: Shift left shift right stay the same (c) the volume of the reaction flash is increased: Shift left shift right (d) the temperature is lowered: Shift left shift right stay the same stay the same (e) add he (g) while keeping the volume fixed: For this reaction the value of kp is 6. 5 x 10 -3 at 723 k. for the following mixture indicate. If the system is at equilibrium, and if it is not, indicate the direction in which the reaction. Pressure of nh3 = 60 atm, pressure of h2 = 150 atm, pressure of n2 = 80 atm.

Can you please explain how to get to the answer?

6. The pressure on each of the following systems is increased by decreasing the volume of the container. Explain whether each system would shift left, right, or stay the same.

a. 2 SO2 (g) + O2 (g) â 2 SO3 (g) (1 mark)

b. H2 (g) + I2 (g) â 2 HI(g) (1 mark)

c. CaCO3 (s) â CaO(s) + CO2 (g) (1 mark)

d. AgCl(s) â Ag1+(aq) + Cl1- (aq) (1 mark)

How could you alter the following to make the equilibrium below shift to the left:

2CO(g) + O2(g) 2CO2(g) + 566 kJ

a) [CO]

b) pressure

c) temperature>2NH(G)

Changing the volume of the system alters the equilibrium position of this equilibrium:N2(G)+3H2(G)------ But a similar change has no effect on this equilibrium: H2(G)+ Cl2(G)----> 2HCl (g) Explain
