We discuss the properties of quantum state reactivity as a measure for quantum correlation. This informa-tion geometry-based definition is a generalization of the two qubit construction of Schumacher to multipartitequantum states. It requires a generalization of information distance to information areas as well as to higher-dimensional volumes. The reactivity is defined in the usual chemistry way as a ratio of surface area to volume.The reactivity is an average over all detector settings. We show that this measure posses the key features re-quired for a measure of quantum correlation. We show that it is invariant under local unitary transformations,non-increasing under local operations and classical communication, and monotonic. Its maximum bound can'tbe obtained using only classical correlation. Furthermore, reactivity is an analytic function of measurementprobabilities and easily extendable to higher multipartite states.
