False statements :
Product formation is always favored in a reaction with a positive Ho and a negative So
When Ho is positive and So is negative then the reaction will not be spontaneous and it is
not even favorable thermodynamically. Hence this statement is false.
An exothermic reaction is always spontaneous.
For most of the reaction this statement hold true however, it still depends on temperature and entropy
So it is false.
Entropy decreases as the temperature decreases .
If temperature increases then there will be more randomness, hence more entropy.
True statements :
For an endothermic reaction an increase in temperature results in an increase in the equilibrium
constant.
In an endothermic reaction the reaction moves forward when temperature increases.
The entropy of a substance decreases when a liquid freezes to form a solid at any temperature.
The system is going from more disorder to less disorder hence entropy decreases.
A reaction will have an equilibrium constant that is less than one if Go for the reaction is
positive.
Go = -RT ln Keq is the actual relation, when it is positive all the reactants are converted to products
usually.
