Re: CV or CP
Cv is used when a reaction is occurring at a constant volume and Cp is used when a reaction is occurring at a constant pressure.

Re: CV or CP
You use Cv when the reaction is going under a constant Volume (isometric) and Cp when the pressure is not changing in the reaction (isobaric).

Re: CV or CP
Cp is when a reaction is occurring at constant pressure and Cv is when a reaction is occurring at constant volume. The molar heat capacities of an ideal gas can be found on the Constants and Equations sheet where Cp= 5/2R and Cv=3/2R.

Re: CV or CP
Cv refers to constant volume, whereas Cp refers to constant pressure. If anything, the problem may describe which one you're going to use depending on whether the system is described as isobaric(constant pressure) or Isometric (constant volume).
