Resumen:
An ideal mixture of parahydrogen (with nuclear spin K=0) and orthohydrogen (with K=1), in statistical weights 1/4 and 3/4, respectively, is used as a test ground for the existence of nonextensivity in chemical physics. We report on a new bound on the nonextensivity parameter q−1 that characterizes generalized thermostatistics à la Tsallis. This bound is obtained on the basis of laboratory measurements of the specific heat of hydrogen. Suggestions are advanced for the performance of improved measurements.
