The equations below will be provided on the exam as shown below (no annotation). Note that many of the equations below only apply under certain circumstances. You should make sure you understand the concepts embodied in each of these equations and thus the conditions under which they apply. These equations are all from chapters 8 and 9. There are additional equations you are responsible for (law of mass action for instance), but I believe that people have a grasp of them from their work prior to the midterm. You may be asked to use the following equations to derive new relationships.

q_v = nC_vDT, dq_v = nC_vdT

q_p = nC_pDT, dq_p = nC_pdT

DE = q + w, dE = dq + dw

H º E + PV

DE = nC_VDT, dE = nC_vdT

DH = nC_pDT, dH = nC_pdT

DH=q_p, dH = dq_p

DE = q_v, dE = dq_v

DS^Tot ³ 0

S = k_BlnW, W=(cV)^N

GºH-TS

DG = DH – TDS

DG = DG^o +RTlnQ

DG^o = -RTlnK

P₁ = X₁P₁*

G₁ = G₁^* + n₁RTlnX1
