Detailed information about the equation 2H2SO4 -> 2H2 + 2SO2 + O2 -> : The above chemical equation shows that when 2 moles of sulfuric acid (H2SO4) decompose, it will produce 2 moles of hydrogen (H2), 2 moles of sulfur dioxide (SO2), and 1 mole of oxygen (O2).
-
Reaction conditions: The decomposition of H2SO4 usually occurs at high temperatures.
-
Reaction process: When sulfuric acid is heated, it decomposes and produces hydrogen gas, sulfur dioxide gas, and oxygen gas. As it is a decomposition reaction, it requires high temperature to occur.
-
Phenomenon occurs: When the reaction occurs, we will see gas bubbles appear from the H2SO4 solution. These are the hydrogen, sulfur dioxide and oxygen gases produced from the decomposition reaction.
