Which of the following best defines the instantaneous rate of a chemical reaction at a particular moment in time?
(a) The slope of a straight line connecting that point on the curve to the origin
(b) The average rate calculated over a short but finite time interval immediately following that moment
(c) The slope of a tangent drawn to a concentration–versus–time curve at that moment
(d) The slope of a tangent drawn to a rate–versus–time curve at that moment
