ENTHALPY CHANGE OF REACTION, STANDARD CONDITIONS & STANDARD ENTHALPY CHANGES
ENTHALPY CHANGE OF REACTION: The total energy content of the system is called its enthalpy. It is given the symbol H. It is impossible to obtain an absolute value of energy of the system at any instant, but it is possible to measure the enthalpy change when energy is transferred from the system to the surroundings or vise versa. The enthalpy change is given the symbol H. Mathematically H = H - H (Product) ...
