Question

The standard cell potential ($$E^\circ_{cell}$$) of a fuel cell based on the oxidation of methanol in air that has been used to power a television relay station is measured as $$1.21 \, 	ext{V}$$. The standard half cell reduction potential for $$O_2/H_2O$$ ($$E^\circ_{O_2/H_2O}$$) is $$1.229 \, 	ext{V}$$. Choose the correct statement:

Accepted Answer

A. The standard half cell reduction potential for the reduction of $$CO_2$$ ($$E^\circ_{CO_2/CH_3OH}$$) is $$19 \, 	ext{mV}$$
