the concentration of products and reactants when the time is NOT as equilibrium.
what is the reaction quotient?
300
this reaction is forward spontaneous at low temperatures.

example of a dipole-dipole bond.
(answers may vary)
what is O-H / N-H / F-H ?
300
consider the reaction: N2(g) + 3 H2(g) 
2 NH3(g)
where ΔH = -92.22 kJ and ΔS = -198.75 J/K
is the reaction spontaneous at 298.15 K and 427.15 K?
@ 298.15 K --> ΔG = -32.96 kJ , yes spontaneous
@427.15 K --> ΔG = -7.324 kJ, yes spontaneous

the formula / definition of a hydrogen bond
what is:
X-H ~~ :X
a hydrogen that is covalently bonded to a N, O, F and is attracted to the lone pair on a different N, O, F.

a system that will do work for you.
what is -ΔG / exergonic reaction?
500
the reasoning behind dispersion forces.
what is an instant in time where the electrons in one atom are all pushed to one side, creating an instantaneous dipole, which, in turn, causes the electrons in a different atom to all push to one side creating an induced dipole that is then attracted to the partial positive in the instantaneous dipole?
