A single firm monopolises a market. There are ten identical consumers in the market (indexed i =1 to 10), each with the following demand: $q_i = 100 - P$ The firm has constant marginal costs, MC = 10. Calculate the following: a. The firm's profit maximising uniform price ($P_m$) as well as quantity ($Q_m$) that will be sold at this price. b. Calculate producer surplus (PS), the consumer surplus (CS) and the inefficiency that exist in the market (DWL). c. Sketch a well labelled graph for the uniform price monopoly firm.

Problem 6 The reaction of cyanic acid and monohydrogen phosphate to form cyanate and dihydrogen phosphate along with the $K_a$ for each acid are shown below. \begin{tabular}{|l|l|} \hline cyanic acid, HCNO & $K_a = 2.19 \times 10^{-4}$ \\ dihhydrogen phosphate, $H_2PO_4^-$ & $K_a = 6.32 \times 10^{-8}$ \\ \hline \end{tabular} $HCNO_{(aq)} + HPO_4^{2-}_{(aq)} \rightleftharpoons CNO^-_{(aq)} + H_2PO_4^-_{(aq)}$ cyanic acid monohydrogen phosphate cyanate dihydrogen phosphate a. Label the acid/base on each side of the equation and connect conjugate acid/base pairs. b. Write a $K_a$ expression for the acid AND for the conjugate acid. Remember to use the acid dissociation reaction in water for each of the acids (the acid and the conjugate acid) when determining the $K_a$ expression. Do not use condensed structures. Clearly show which structure is in the numerator and the denominator. c. What is the $pK_a$ for both the acid and the conjugate acid? d. Which one of these 2 acids is the weaker one?
