The radionucleide $${}_{90}^{234}Th$$ undergoes two successive $$\beta$$ -decays followed by one $$\alpha$$-decay. The atomic number and the mass number respectively of the resulting radionucleide are

For the reaction A + 2B $$\to$$ C, rate is given by R = [A] [B]² then the order of the reaction is

Units of rate constant of first and zero order reactions in terms of molarity M unit are respectively

The integrated rate equation is Rt = log C₀ - log C_t . The straight line graph is obtained by plotting
