Consider the following system at equilibrium where ? ??#A 6.1 k, and Ke-?S4 , at 29k 2 NO (g)-Br, (g) 2 NOBr (g) If the TEMPERATURE on the equilibrium system is suddenly decreased alue of Ke ??] A. Increases B. Decreases C. Remains the same The value of Qe A. Is greater than Kc B. Is equal to Kc C. Is less than Kc A. Run in the forward direction to restablish equilibrium. B. Run in the reverse direction to restablish equilibrium C. Remain the same. Already at equilibrium. The reaction must: The concentration of Br2 will:A B. Decrease C. Remain the same

Explanation / Answer

It is an exotheriex reaction. The temperature increases with the formation of product.

If the temperature is decreased, according to the le chatelier's principle, in order to maintain equilibrium the reaction will proceed in the forward direction.

Since the concentration of product will increase, Kc will increase.(Kc is the ratio of products and reactants at equilibrium)

Forward reaction takes place so Qc is less than Kc.

Concentration of Br2 will decrease as the forward reaction occurs.

The sencos has to be done is a similar manner. On increasing temperature, according to le chatelier's principle, in order to maintain equilibrium the reaction will shift to backward direction. Kc will decrease and concentration of I2 will increase. Qc will be greater than Kc since the reaction is proceeding in backward direction.
