HCl and I2 are placed in a reaction vessel. The endothermic forward reaction
begins, and after a period of time, the system reaches equilibrium.
2HCl(g) + I2(s) --> 2 HI(g) + Cl2(g)
A change is made to shift the equilibrium: the external pressure is increased, so
that the volume of the container decreases. Use LeChatelier's Principle to predict
the shift in the equilibrium.
Specifically: how would increasing the volume of the equilibrium mixture affect
the concentration of HCl gas? - answer increase
Equilibrium constants were measured for a series of reaction of the general type:
AB + CD -> AD + BC.
These equilibrium constant values are shown below. In which reaction is the
concentration of products the smallest at equilibrium? - answer K = 9.7 x 10^-8
HCl and I2 are placed in a reaction vessel. The endothermic forward reaction
begins, and after a period of time, the system reaches equilibrium.
2HCl(g) + I2(s) --> 2 HI(g) + Cl2(g)
, A change is made to shift the equilibrium: the heat is removed by placing the
reaction vessel in an ice bath. Use LeChatelier's Principle to predict the shift in the
equilibrium.
Specifically: how does decreasing the temperature affect of HI? - answer decrease
HCl and I2 are placed in a reaction vessel. The endothermic forward reaction
begins, and after a period of time, the system reaches equilibrium.
2HCl(g) + I2(s) --> 2 HI(g) + Cl2(g)
A change is made to shift the equilibrium: more HCl gas is added to the reaction
container. Use LeChatelier's Principle to predict the shift in the equilibrium.
Specifically: how would adding HCI to the reaction container affect the amount of
I2 solid in the reaction mixture? - answer Decrease
