Question 1
1. One of the reactions involved in the
production of nitric acid is:
4NH3(g) + 502(g) - 4NO(g) + 6H20(g) + heat
For maximum yield of NO(g) at equilibrium,
this reaction should be carried out:
at high temperature and low pressure.
at high temperature and high pressure.
at low temperature and high pressure.
at low temperature and high pressure.
Question 2
Consider the following system:
H2(g) + I2(g) F 2HI(g)
A quantity of pure HI (hydrogen iodide) was
placed in an empty vessel at 731 K and the
system was allowed to come to equilibrium.
An increase in the reaction vessel would:
cause the reaction to proceed to completion.
cause the production of more H2.
cause the production of more HI.
cause no effect on the equilibrium.
Question 3
The equilibrium constant for a chemical
reaction can be changed by:
increasing the temperature.
adding a catalyst.
increasing the concentration of the products.
increasing the concentration of the reactants.
