Chapter 15, Problem 65P

(a)

Interpretation Introduction

Interpretation: The chemical equation for the conversion of carbon monoxide and hydrogen to methanol should be written.

Concept Introduction:

Reduction reaction is defined as addition of hydrogen or reduction in the oxidation state of any atom in the starting molecule. Since, reduction is addition of hydrogen thus, it takes place in the presence of hydrogen. Similarly, oxidation is addition of oxygen, which takes place in the presence of oxygen.

(b)

Interpretation Introduction

Interpretation:

The reaction ofhydrogen-oxygen fuel cell should be written.

Concept Introduction:

Fuel cells have source of fuel as e.g. hydrogen and oxygen. Hydrogen is oxidized electrochemically inside the fuel cell to produce a potential difference i.e. a voltage which monitors the flow of current in the circuit.
