Question

Use Keterences if needed the to important valnea for thia acceas Consider the following system at equilibrium where ?11° =-16.1 kJ, and Ke-154, at 298 K 2 No (B) Bra()2 NOBr (3) If the TEMPERATURE on the equilibrium system is suddenly increased The value of Ke A Increases B. Decreases C Remains the same The value of QcA Is greater than B. Is equal to Ke C. Is tess than Kc reg The reaction must:A 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. A Increase B Decrease C Remain the same The concentration of Bra will: submithriswer

Explanation / Answer

1. The value Kc decreases with increase in temperature.

2. The value of Qc will decreases and it will be equal to the new value of Kc.

3. As the value of Kc decreases, so the reaction must run in reverse direction to reestablish the equilibrium.

4. As Br2 is in reactant side and increase in temperature favors reversed reaction, so the concentration of Br2 will increase.
