Re: Cp v.Cv
CV is the molar specific heat at constant volume, and CP is the molar specific heat at constant pressure.
So usually you will be told that a reaction is occurring at either constant pressure or constant volume, and you probably will be given the initial and final value if you are expected to use ΔP or ΔV for something

Re: Cp v.Cv
You will be told whether a reaction is occurring at constant pressure or volume, and based on that you use the corresponding specific heat. This specific heat will be greater for constant pressure, as more heat energy is required to raise the temperature due to the fact that some of this heat energy will be used to do work of expansion. For constant volume, however, no work of expansion can be done and all the heat energy put into the system is used to raise the temperature.

Re: Cp v.Cv
Cp refers to the molar heat capacity of gases at constant pressure (isobaric), which is equal to 5/2 times ideal gas constant R. Cv is at constant volume instead (isochoric), and it is a smaller value at 3/2 times R.

Re: Cp v.Cv
In every question in the HW it is stated whether constant pressure or constant volume is occurring. if constant pressure 5/2R and constant Volume is 3/2R

Re: Cp v.Cv
Cp is used when there is constant pressure while Cv is used when there is constant volume
