The standard enthalpy of reaction, often denoted as \\( \\Delta H^\\circ \\), is the change in enthalpy that occurs during a chemical reaction at standard conditions. Standard conditions typically refer to a temperature of 25 degrees Celsius (298.15 K), a pressure of 1 atmosphere (101.3 kPa), and concentrations of 1 mol/L for solutions.
