3. Answer all sections (i) - (iv). 1 mole of ethanol (C2H5OH) and 1 mole of ethanoic acid (CH;COOH) were reacted at 25 °C, in a non- aqueous solvent, until equilibrium was reached. It was subsequently determined that 0.33 moles of ethanol remained at equilibrium. (i) Write an equation for the reaction. (ii) Write an expression for the equilibrium constant, Kc, for the reaction and calculate its value. Subsequently a further 3 moles of C2H5OH was added to the solution. (ii) Determine the concentrations of all the species present when equilibrium is restored.

please answer fast! Cyclohexane (C6H12) undergoes a molecular rearrangement in the presence of AIC13 to form methylcyclopentane (MCP) according to the equation: C_{6}*H_{12} = MCP If K_{C} = 0.143 at 25°C for this reaction, predict the direction in which the system will shift if the initial concentrations of C6H12 and MCP are 0.200 M and 0.100 M, respectively. The system A) will shift right B) will shift left. C) is already at equilibrium. D) is not at equilibrium and will remain in an unequilibrated state.
