What are half-reactions?</h3>
The half-reaction method is a way to balance redox reactions. It involves breaking the overall equation down into an oxidation part and a reduction part.
a)
→
= 
= -0.83 - (-2.71) =1.88V
b)
→
= 
=-0. - (0.8) =-0.8V

The correct answer to this question is letter "B) 8.4 × 10-4 M."
2CO+O2<->2CO2
-x -x +x
It started as 2CO2 so +x, then it decomposed into 2CO and O2, so-x
2CO-oxidized, O2-Oxidized, 2CO2-reduced
the easiest way is to look at the equation, so if we have some reactant and no product
A<->2C+D
-x +2x +x
so if we had product concentration, and no reactant concentration
3A<-> C+D
+3x -x-x
