Question

Which type of rate is given by the slope of conc. of reactants vs time curve at a particular point?

Answer 1

The type of rate given by the slope of the concentration of reactants vs. time curve at a particular point is the instantaneous rate of reaction.

The instantaneous rate represents the rate of reaction at a specific moment in time. It is determined by finding the slope of the tangent drawn to the concentration vs. time curve at that particular point.

Mathematically, it is expressed as

\[\ce{Instataneous rate = -\frac{d[Reactant]}{dt}}\]

The negative sign indicates the concentration of reactants is decreasing with time.
