The time (t) (in seconds) taken for a chemical reaction varies directly as the square of the concentration (c) (in mol\,L^{-1}) and inversely as the temperature (T) (in kelvin). When (c = 0.2) and (T = 300\) the reaction takes (t = 12\) s. Find the temperature required for the reaction to take (t = 8\) s if the concentration is increased to (c = 0.3\).
