Which factor changes the value of Kc?
Pressure
Concentration
Temperature
Catalyst
2.
Units of Kc for N2 + 3H2 ⇌ 2NH3:
mol-2 dm6
mol2 dm-6
no units
mol dm-3
3.
For CaCO3(s) ⇌ CaO(s) + CO2(g), Kp equals:
p(CaO)p(CO2)/p(CaCO3)
1/p(CO2)
p(CO2)2
p(CO2)
4.
For an exothermic reaction, raising temperature makes K:
increase
decrease
stay the same
equal 1
5.
A gas has mole fraction 0.25 in a mixture at 200 kPa. Its partial pressure is:
25 kPa
800 kPa
50 kPa
150 kPa
6.
ΔStotal is related to K by:
ΔStotal = R ln K
ΔStotal = K/RT
ΔStotal = −RT ln K
ΔStotal = ln K / R
7.
Which statement best describes Homogeneous equilibrium?
An equilibrium where all species are in the same phase.
The pressure a gas in a mixture would exert if it alone occupied the container; p = mole fraction × total pressure.
The ratio of equilibrium concentrations of products to reactants, each raised to its stoichiometric power.
Moles of one gas divided by total moles of gas in the mixture.
8.
Which statement best describes Equilibrium constant, Kc?
Moles of one gas divided by total moles of gas in the mixture.
The relative amounts of products and reactants present at equilibrium.
An equilibrium where species are in different phases; pure solids and liquids are left out of K.
The ratio of equilibrium concentrations of products to reactants, each raised to its stoichiometric power.
9.
Which statement best describes Equilibrium constant, Kp?
An equilibrium where species are in different phases; pure solids and liquids are left out of K.
The equilibrium constant expressed using partial pressures of gases.
The relative amounts of products and reactants present at equilibrium.
The ratio of equilibrium concentrations of products to reactants, each raised to its stoichiometric power.
10.
Which statement best describes Position of equilibrium?
The ratio of equilibrium concentrations of products to reactants, each raised to its stoichiometric power.
The pressure a gas in a mixture would exert if it alone occupied the container; p = mole fraction × total pressure.
Moles of one gas divided by total moles of gas in the mixture.
The relative amounts of products and reactants present at equilibrium.
