reaktiosuhteen

Reaktiosuhde, also known as stoichiometric ratio, is a fundamental concept in chemistry that describes the quantitative relationship between reactants and products in a chemical reaction. It is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only rearranged.

The reaktiosuhde is typically expressed as a ratio of the coefficients from a balanced chemical equation. For example, in the reaction between hydrogen and oxygen to form water, the balanced equation is:

2 H2 + O2 → 2 H2O

The reaktiosuhde for this reaction is 2:1:2, meaning that 2 moles of hydrogen react with 1 mole of oxygen to produce 2 moles of water. This ratio ensures that all reactants are completely consumed and all products are formed according to the stoichiometry of the reaction.

Understanding reaktiosuhde is crucial for predicting the amounts of products that can be formed from given amounts of reactants, as well as for determining the limiting reactant in a reaction mixture. It is a key concept in stoichiometry, the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions.
