Question
The equilibrium constant of a system, K, can be related to the standard free energy change, AGO, using the following equation: AG-RT In K where I is a specified temperature in kelvins (usually 298 K) and R is equal to 8.314 J/(K.mol). Under conditions other than standard state, the following equation applies: AG = AG° + ᎡᏆ ln Q In this equation, Qis the reaction quotient and is defined the same manner as K except that the concentrations or pressures used are not necessarily the equilibrium values. Part A Acetylene, C₂ H2, can be converted to ethane, C₂H6, by a process known as hydrogenation. The reaction is C₂H₂(g) + 2H₂(g) = C₂H6(g) Given the following data at standard conditions (all pressures equal to 1 atm and the common reference temperature 298 K), what is the value of Kp for this reaction? 9A V—| ΑΣΦ Substance Express your answer using two significant figures. ►View Available Hint(s) t C₂ H₂(g) H₂(g) C₂H6(g) P ?
