Which type of reaction is the Haber process?
Haber process is a type of
exothermic reaction
because heat energy is released during the formation of ammonia gas from nitrogen and hydrogen gases….
What are reaction types?
The five basic types of chemical reactions are
combination, decomposition, single-replacement, double-replacement, and combustion

energy source aerobically
.
What is heterogeneous oxidation?
Heterogeneous oxidation
increases the oxidation state of particulate carbon
, with the rate of increase determined by the detailed chemical mechanism. … In contrast to the oxidation state increase, the rate of carbon loss is nearly uniform among most systems studied.
Which type of reaction occurs in cathodic areas?
Hydrogen ion reduction
, or hydrogen evolution, has already been discussed. This is the cathodic reaction that occurs during corrosion in acids. Oxygen reduction is a very common cathodic reaction, since oxygen is present in the atmosphere and in solutions exposed to the atmosphere.

electrochemical reaction,
any process either caused or accompanied by the passage of an electric current
and involving in most cases the transfer of electrons between two substances—one a solid and the other a liquid.
