2. The reaction Fe3+ (aq) + SCN (aq) → FeSCN2+ (aq) produces a dark red color resulting from the formation of FeSCN2+. a. How does the color change if you add more SCN to a solution at equilibrium? (lighter or darker) b. How does the color change if you remove Fe3+ by reacting it with fluoride ions? c. If a reaction proceeds forward when you heat it, and reverse when you cool it, the reaction is [endothermic exothermic).

uestion Completion Status: N204(8) <...> 2 NO 2(8) At 25°C, 0.11 mole of N204 reacts to form 0.10 mol of N204 and 0.02 mole of NO 2. At 90'C, 0.11 mole of N204 forms 0.050 moles of N204 and 0.12 mole of NO2. From this data, we can conclude The reaction is exothermic the equilibrium constant for the reaction above increases with an increase in temperature. N204 molecules react faster at 25°C than at 90°C. O None of these are...
