ideal gases and reactions

[905084274]

How do ideal gases affect a reaction? I know that it may change the C value such as 5/2R or 3/2R

There are certain elements of a system that are true when the observed substance is an ideal gas. Cv and Cp do have specific equations, depending on whether that gas is monoatomic, linear, or nonlinear (equations are on equation sheet). There are other factors that are true, such as ΔU=0 for isothermal work of an ideal gas (so q=-w). Also, we can use PV=nRT to calculate any term in that equation (only for ideal gases).
