Indicate whether the addition of each of the following increase or decrease the FeSCN2+ in an equillibrium mixture. Explain Add IncreasesFeSCN2+ DecreasesFeSCN2+ Reason a. Fe3+ b. Heat c. Cl- d. Cooling e. SCN- Indicate whether the addition of each of the following increase or decrease the FeSCN2+ in an equillibrium mixture. Explain Add IncreasesFeSCN2+ DecreasesFeSCN2+ Reason a. Fe3+ b. Heat c. Cl- d. Cooling e. SCN-
Explanation / Answer
Add IncreasesFeSCN2+ DecreasesFeSCN2+ Reason a. Fe3+ IncreasesFeSCN2+ as per Le-chatlierprinciple b. Heat DecreasesFeSCN2+ the backward reaction is endothermic c. Cl- DecreasesFeSCN2+ Cl- thearatically decreses the con ofFe3+ d. Cooling IncreasesFeSCN2+ the farward reaction isexothermic e. SCN- IncreasesFeSCN2+ as per Le-chatlier principle,i (increse any of the reactents shifts the equilibrium towards products ) both the equilibria involved menctioned bellow Fe3+ (aq) + 2SCN2+ <==> FeSCN2+ + Heat FeCl3(aq)<=> Fe3+ (aq)+ 3Cl- (aq)
