A → X The enthаlpy chаnge fоr the reаctiоn represented abоve is ΔHT. This reaction can be broken down into a series of steps as shown in the diagram: A cyclic diagram shows the relationship among various enthalpy. An arrow from A to B is labeled, Delta H subscript 1 and a second one from A to X is labeled, Delta H subscript T. A third arrow from B to C is labeled, Delta H subscript 2, and a fourth arrow from C to X is labeled Delta H subscript 3. A relationship that must exist among the various enthalpy changes is
