<Chapter 19 - Attempt 1 Item 15 < 15 of 10 (> I Review | Constants | Periodic Table The equilibrium constant of a system, K, can be related to the standard free energy change, AG, using the following equation: Part A AG° = -RT In K where T is a specified temperature in kelvins (usually 298 K) and Ris equal to 8.314 J/(K - mol). Acetylene, C2 H2, can be converted to ethane, C3Hs, by a process known as hydrogenation. The reaction is Under conditions other than standard state, the following equation applies: CH2(g) + 2H2(g) = CHo(g) AG = AG" + RT In Q Given the following data at standard conditions (all pressures equal to 1 atm and the common reference temperature 208 K), what is the value of Kp for this reaction? In this equation, Q is the reaction quotient and is defined the same manner as K except that the concentrations or pressures used are not necessarily the equilibrium values.
