If delta H rxn is -75.2 kJ, 2NO(g) + Cl2 (g) <---> 2NOCl(g) A scientist places four moles of nitrogen monoxide and two moles of chlorine gas into flask A and the same amounts into Flask B, then allows the systems to reach equilibrium. Flask A is at 25 degrees Celsius and Flask B is at 200 degrees Celsius A) In which flask will the reaction occur faster? Explain. B) In which flask will the reaction occur to a greater extent? Explain.

Answer #1

2NO(g) + Cl2 (g) <---> 2NOCl(g)                 H rxn is -75.2 kJ

As the given reaction is exothermic in nature. It requires low temperature, in forqward direction that is towards products formation.

Flask A is at low temperature which is is at 25 degrees Celsius.

Flask B is at high temeperature which is at 200 degrees Celsius.

Flask A has faster rate of reaction and also has greater extent of reaction.
