The heat capacity of 1 gram of a substance is known as its specific heat (J/g-K). The following equation relates the specific heat of a substance, the temperature change, the mass of the substance, and how much energy was put into the system: how to develop interpersonal communication skills You will not need to be able to calculate the enthalpy directly; in chemistry, we are only interested in the change in enthalpy, or ?H. ?H = H final - H initial or ?H = H(products) - H(reactants) Tables of enthalpies are generally given as ?H values..

  • When a process occurs at constant pressure, the heat evolved (either released or absorbed) is equal to the change in enthalpy. Enthalpy (H) is the sum of the internal energy (U) and the product of …
  • It varies, for example, if you change the temperature of the reaction, add a catalyst, or change the catalyst. The rate constant is constant for a given reaction only if all you are changing is the concentration of the reactants. You will find more about the effect of temperature and catalysts on the rate constant on another page. Note: If you want to follow up this further look at rate
