This project was preformed to supply Libretext authors with videos on General Chemistry topics which can be used to enhance their projects. Also, these videos are meant to act as a learning resource for all General Chemistry students . Video Topics The instantaneous rate of a reaction is the reaction rate at any given point in time. Rate of reaction is = - 1/r d[R]/dt An instantaneous rate is defined as the negative slope of the line on this graph. As the period of time used to calculate an average rate of a reaction becomes shorter and shorter, the average rate approaches the instantaneous rate.
