Question

State Standard Enthalpy of reactions?​

Answer 1

Explanation:

The standard enthalpy of reaction (denoted ΔHr⦵) is the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, when all reactants and products are in their standard states. −vA A + −vB B + ... → vP P + vQ Q ... In this equation, vB is the stoichiometric number of entity B.

Answer 2

$\huge\red{\underline{{\boxed{\textbf{Answer}}}}}$

The standard Enthalpy of reaction is the enthalpy change for a react when all the participating substances are in thier standard states.

The standard state of a substance at a specified temperature is its pure form at 1bar.
