A) increase the E and shift equilibrium to the right
B) lower the E and shift equilibrium to the right
C) lower the E and shift equlibrium to the left
D) increase the E and shift equilibrium to the left
Correct Answer: A
Solution :
[a] \[Zn(s)+2{{H}^{+}}(aq)\rightleftharpoons Z{{n}^{2+}}(aq)+{{H}_{2}}(g)\] \[{{E}_{cell}}=E{{{}^\circ }_{cell}}-\frac{0.059}{2}\log \frac{[Z{{n}^{2+}}][{{H}_{2}}]}{{{[{{H}^{+}}]}^{2}}}\] Addition of \[{{H}_{2}}S{{O}_{4}}\] will increase \[[{{H}^{+}}]\]and \[{{E}_{cell}}\] will also increase and the equilibrium will shift towards RHSYou need to login to perform this action.
