Lоng-fоrm Questiоn 1 (write your аnswers on your piece of pаper) (а) Consider the gas phase association of potassium atoms: Suppose you start with 2 moles of K (g) and you select 1 bar as the reference state. Derive an expression for the equilibrium constant, , in terms of the extent of reaction at equilibrium, , and the total pressure, . What is the value of if you are at a temperature where = 0.5 and = 1.5 bar? (b) The following is a plot of the Gibbs energy as a function of the reaction extent for the gas phase reaction at 420 K and a total pressure of 1 bar. The minimum in the Gibbs energy is indicated on the plot at . The extent of reaction is defined to range . At equilibrium, what is the partial pressure of NO2, ? Long-form Question 2 (write your answers on your piece of paper) The pressure for the two components in a binary solution are given by: Derive expressions for and in terms of and the constant .
