Unit 2 - Chemical Equilibrium
10. Given the reaction: A + B
C + D
When 1.0 mole of A is combined with 1.0 mole of B, an equilibrium is established in
which [A] = 0.2 M, [B] = 0.2 M , [C] = 0.8 M and [D] = 0.8 M
If, at the same temperature, 1.0 mole of C and 1.0 mole of D is combined. When
equilibrium is established, determine what the following concentrations will be:
[A] =______M, [B] = ______ M , [C] = ______ M and [D] = ______ M
11. Given sufficient activation energy, a system not at equilibrium will eventually move
toward __________________________________________.
12. Systems will tend toward a position of ________________________________ enthalpy.
13. Systems will tend toward a position of ________________________________ entropy.
14. Tell whether each of the following is endothermic or exothermic and state which has
minimum enthalpy, the reactants or the products:
a.

∆H = -92.5 kJ
2(g)
3(g)

+ 3H
∆H = 92.4 kJ
3(g)
2(g)
2(g)
__________thermic and the ___________________ have minimum enthalpy.

∆H = +25 kJ
2(aq)
2(g)
was proceeding to the right, the enthalpy would be ____________________ing. Is this a
favourable change? _____________.
