Ethyl acetate is synthesized in a nonreacting solvent (not water) according to the following reaction: CH; CO,H+ C,H; OH= CH3CO,C,H; + H20 K = 2.2 Acetic acid Ethanol Ethyl acetate For the following mixtures (a-d), will the concentration of H2 O increase, decrease, or remain the same as equilibrium is established? c. [CH; CO, C, H5] = 0.88 M , [H2O] = 0.12 M, [CH3 CO,H] = 0.044 M, [C,H, OH] = 6.0 M increase decrease Oremain the same d. [CH3 CO, C,Hs] = 4.4 M, [H2O] = 4.4 M, [CH, CO,H] = 0.88 M , [C,H; OH] = 10.0 M O increase decrease remain the same e. What must the concentration of water be for a mixture with [CH3 CO2 C,Hs] = 1.0 M, [CH; CO,H] = 0.10 M , and [C,H; OH] = 6.0 M to be at equilibrium?

Given the reaction: CO(NH2),(s) + H2O(g) = CO2(9) + 2NH3(g) -- Kp If this reaction system is initially at equilibrium and a catalyst is added, the new position of equilibrium will be = 1.39 at 500 K The value of K, for the given reaction at 600 K is The reaction CO(NH₂)₂(s) + H₂O(g) → CO₂(g) + 2 NH₂(g) is -- A flask containing CO₂(g), NH₂(g), CO(NH₂)₂(s) and H₂O(g) is initially at equilibrium at 500 K. When the flask is heated to 600 K, the amounts of CO(NH₂)₂(s) and H₂O(g) decrease and the amounts of CO₂(g) and NH₂(g) increase. This means that:

Magnitude of the Equilibrium Constant 7 of 22 Review | Constants | Periodic Ta Part D For a reaction For the reaction aA + bB = cC + dD CO(g) + H2O(g) = H2(g) + CO2(g), K = 4.24 at 800 K the equilibrium constant K is defined as the ratio of products to reactants at equilibrium: what can be said about this reaction at this temperature? K [C]°D]* • View Available Hint(s) [A]*[B]* Because K represents the ratio of products to reactants, the magnitude of K is an indicator of the levels of products and reactants present when the reaction is at equilibrium. Some chemical reactions proceed almost fully to product, whereas other chemicals hardly react with each other at all, or react so as to have significant amounts of both reactants and products at equilibrium. O The equilibrium lies far to the right. O The reaction will proceed very slowly. O The reaction contains significant amounts of products and reactants at equilibrium. O The equilibrium lies far to the left.
