Question

explain the electrochemical reaction and thermo chemical reaction

answer​

Answer 1

Answer:

In fact, all chemical reactions result from a shift in the electron structure of atoms, and free electrons can combine with particles of matter (reduction) or be released by them (oxidation). ... The substances that take part in electrochemical reactions, called electrolytes or ionic conductors,

Answer 2

Thermochemical reactions involve the absorption or evolution of heat. Electrochemical reactions need electricity.

Explanation:

• The chemical reaction that needs electricity is called an electrochemical reaction.
• For example, decomposition of $H_{2}O$ $into$ $H_{2} \ and \ O_{2}$ .
• Here, electrons flow between a solid electrode and a substance, such as an electrolyte.
• A thermochemical reaction may release or absorb energy, and a phase change may do the same, such as in melting and boiling.
• For example,

                               $\ \\\\\\\\2H_{2}(g) \ + \ O_{2} (g) \ \ -> \ \ 2H_{2} O(l) \ + \ 571.6kJ\\\\N_{2}(g) \ + \ 3H_{2} (g) \ \ -> \ \ 2NH_{3}(g) \ + \ 92kJ$
