Spontaneity of Reactions

Whether a reaction is spontaneous
is dependent on the changes in
which two concepts?

Entropy is a measure of

Increasing entropy comes from

Increasing the temperature of a system
does what to the entropy?

if enthalpy change is positive
compare the relative enthalpy of the
reactants with the products

if enthaply change is positive
describe what you would feel
as the reaction proceeds

Sponaneity is favoured with
what change in enthaply?

Describe an exothermic reaction

spontaneous or not?
Entropy increases
and
enthaply change is negative

spontaneous or not?
Entropy decreases
and
enthaply change is negative

spontaneous or not?
Entropy increases
and
enthaply change is positive

spontaneous or not?
