How can be rate of reaction at a specific in the be determined from a graph of concentration against time ?

The graph of temperature against time is

How can average and instantaneous rates of a reaction can be determined from the plot of concentration versus time?

When is the rate of reaction equal to specific reaction rate ?

What do you understand by rate of a reaction and specific reaction rate ? How the rate of a reaction can be determined ?

What is meant by rate of reaction ? Show that the rate of reaction cannot be determined by dividing the total change in concentration by total time taken.

For a zero-order reaction with rate constant k, the slope of the plot of reactant concentration against time is

How instantaneous rate of reaction is determined?

The rate constant of a specific reaction is independent of the concentration of the reactants.
