What does physical chemistry help us understand?
Why certain processes have a natural tendency to occur
What is the First Law of Thermodynamics about?
Conversion of energy from one form to another
According to the Zeroth Law of Thermodynamics, if A and B are in thermal equilibrium with C, what does it imply?
A and B are also in thermal equilibrium with each other
What does the sign of q and w represent in the First Law of Thermodynamics?
Direction of heat exchange and work done on/by the system
What is Enthalpy a measure of?
Heat content under constant pressure in a system
Why is it important to understand the rate of change in chemical reactions?
To measure the extent and speed of reactions
Why is the standard molar enthalpy of formation of O2(g) equal to 0?
Because there is no change in enthalpy when O2(g) transitions to O2(g).
How is the standard enthalpy of reaction calculated using the standard enthalpies of formation?
{cΔH°f (C) + dΔH°f (D)} - {aΔH°f(A) + bΔH°f(B)}
Which thermodynamic principle explains why some chemical processes are spontaneous?
The second law of thermodynamics
Why do exothermic reactions tend to be spontaneous according to thermodynamics?
Because they have a negative enthalpy change.
Which method is used to determine the standard enthalpy of reaction directly from standard enthalpies of formation?
The Direct method
Why are spontaneous processes unlikely to occur in the opposite direction under the same conditions?
Due to entropy changes favoring only one direction.
