Question

Please answer A,B TCC Learn Library Fe (a)SCN ()PeSCN (a) where the AH-122 kmol The following situation occurs: The reaction is cooled and then maintained at a lower temperature. What would you expect to happen to the equilibrium position? 3 + O More research is needed to determine what will happen here. O The equilibrium will not be affected by this stressor The equilibrium will shift to the right attempting to remove reactant and/or produce more product. OThe equilibrium will shift to the left to remove product or attempt to make more reactant What would you expect to happen to the equilibrium constant? O The equilibrium constant will change since it only a constant if the temperature is maintained O The equilibrium constant is not affected by temperature as that is not part of the equilibrium expressic OThe equilibrium constant will not be affected by this

Explanation / Answer

a. The delta H value i.e the enthalpy change for the reaction is negative which menas that the reaction is exothermic.

Hence by Lee Chatelier's principle, on decreasing the temperature and carrying out the reaction at a lower temperature the equilibrium will shift to to the right attempting to remove the reactant and producing more product. ( option 3rd )

b. The correct option is the 1st option as the equilibrium constant is temperature dependent and for an exothermic reaction, its value increases with decrease in temperature.
