Question

Dinitrogen tetraoxide and nitrogen dioxide are two gases that exist in equilibrium at a range of temperatures. NO? is a reddish brown gas while N?O? is colorless. At High Temperature the red color is strong. At Low Temperature the gas has less color. If we represent the equilibrium as: N?O?(g) ? 2 NO?(g) We can conclude that: 1. This reaction is: A. Exothermic B. Endothermic C. Neutral D. More information is needed to answer this question. 2. When the temperature is decreased the equilibrium constant, K: A. Increases B. Decreases C. Remains the same D. More information is needed to answer this question. 3. When the temperature is decreased the equilibrium concentration of N?O?: A. Increases B. Decreases C. Remains the same D. More information is needed to answer this question.
