Question

For each equilibrium, determine whether the added stress will shift the equilibrium left, right, or if there will be no shift

A. 3 H2 (g) +N2 (g) = 2 NH3 (g), If N2 is added

B. 3 H2 (g) +N2 (g) = 2 NH3 (g), If NH3 (g) is added

C. 3 H2 (g) +N2 (g) = 2 NH3 (g), If a catalyst is added

D. Ca2+ (aq) + CO32- (aq) = CaCO3 (s), if Ca(NO3)2 (aq) is added

E. Ca2+ (aq) + CO32- (aq) = CaCO3 (s), if CaCO3 (s) is added

F. Ca2+ (aq) + CO32- (aq) = CaCO3 (s), if HCl (aq) is added

G. Ca2+ (aq) + CO32- (aq) = CaCO3 (s), if Na2CO3 (aq) is added

A. 3 H2 (g) +N2 (g) = 2 NH3 (g), If N2 is added

the reaction tends towards forward direction

B. 3 H2 (g) +N2 (g) = 2 NH3 (g), If NH3 (g) is added

Reaction procedes towards reverse direction

C. 3 H2 (g) +N2 (g) = 2 NH3 (g), If a catalyst is added

Rate of reaction changes on both sides but equillibrium doest affected

D. Ca2+ (aq) + CO32- (aq) = CaCO3 (s), if Ca(NO3)2 (aq) is added

reaction shifts toward right direction

E. Ca2+ (aq) + CO32- (aq) = CaCO3 (s), if CaCO3 (s) is added

Raction shifts to left direction

F. Ca2+ (aq) + CO32- (aq) = CaCO3 (s), if HCl (aq) is added

H+ reacts with CO32- and forcces CaCO3 to dissolve more i.e reverse direction is favoured

G. Ca2+ (aq) + CO32- (aq) = CaCO3 (s), if Na2CO3 (aq) is added

due to common ion solubility of CaCO3 decreases more CaCO3 ppt forms i.e forward direction
