Correct answer: Option D, <span>
K = 5.04 × 10^52</span>
Reason:
We know that,
Ecell =
,
where n = number of electrons = 2 (in present case)
K = equilibrium constant.
Also, Ecell = <span>+1.56 v
Therefore, 1.56 = </span>
Therefore, log (K) = 52.703
Therefore, K = 5.04 X 10^52
→ 
is the net ionic equation for this reaction.

Answer : The enthalpy of this reaction is, 0.975 kJ/mol
Explanation :
First we have to calculate the heat produced.
where,
q = heat produced = ?
m = mass of solution = 126 g
c = specific heat capacity of water = 
= initial temperature = 
= final temperature = 
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy of this reaction.
where,
= enthalpy change = ?
q = heat released = 1.95 kJ
n = moles of compound = 2.00 mol
Now put all the given values in the above formula, we get:
Thus, the enthalpy of this reaction is, 0.975 kJ/mol
