Work Formulas For Reversible Reactions =- w PexdV For Reaction/ Condensation/Vaporizati on =- w ∆ngRT For varying temperature (solely changing as stated) =- w nR∆T For varying volume =- w P∆V 2. Constant Volume Processes 2. Constant Volume Processes = = ∆U qv CvdT For Perfect Gas: - = Cp Cv nR = w 0 = + = +(- ) ∆H ∆U ∆PV ∆U P2V2 P1V1 *Note: For ∆PV , Table 1 can be applied if necessary 3. Constant Temperature Processes 3. Constant Temperature Processes = = ∆H ∆U 0 =- q w For that, heat is always dependent on work Table 2. Work Formulas for Isothermal Processes For Reversible Reactions =- w nRTlnV2V1 For Reaction/ Condensation/Vaporizati on =- w ∆ngRT *Note: If the equation is not applicable, make your own! 4. Constant Heat (adiabatic) 4. Constant Heat (adiabatic) Processes Processes = q 0 = = ∆U wad w = = ∆U w CVdT...
