Prin electroliza apei s-au obținut 15 L de hidrogen la temperatura de 27 °C şi presiunea de 1,66•10 Pa. Să se determine:
a) masa hidrogenului obținut;
b) echivalentul electrochimic al hidrogenului;
c) energia electrică consumată, dacă electroliza are loc la o tensiune de 5 V.
Pierderile de energie se neglijează.
Se vor lua: constanta universală a gazelor R = 8,3 J/(mol · K); constanta
(numărul) lui Faraday F = 96 500 C/mol.
