[References] pt Use the References to access important values if needed for this question. pt Consider the following system at equilibrium where Ke-154 and H° =-16.1 kJ/mol at 298 K. 2 NO (g) + Br2 (g) 2 NOBr (g) The production of NOBr (g) is favored by: Indicate True (T or False (F) for each of the following. (-B 1. increasing the temperature. -B 2. decreasing the pressure (by changing the volume). 3.increasing the volume. _ B 4, adding NOBr -. B 5, adding Br2 . Submit Answer Try Another Version 1 item attempt remaining

Explanation / Answer

increasing the temperature will reverse the direction of reaction as the given reaction is an exothermic reaction , 1) false

2)decreasing the pressure will also reverse the direction of reaction , as it will shift to side where pressure will be more in this case pressure is more on reactant side , false

3)increasing the volume will favour the formation of ., NOBr as on the product side volume occupied will be low

4)adding NOBr will reverse the direction of reaction due to le chateliar principle , and the reaction moves in reverse direction, false

5)adding Br2 will lead to formation of more product due to li chateliar principle , this is true as reaction proceeds in forward direction
