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

State the rate equation for a first order reaction. Derive the half-life period from the rate equation. A first order reaction takes 69.3 minutes for 50% completion. How much time will be needed for 80% completion?

A water fall discharges 60 litres of water per sec from a vertical height of 200 m . Assuming that all the energy due to fall is converted to heat and is retained by the falling water , find (i) the quantity of heat produced per sec and (ii) rise in temperature of water .
