Give an example of 1st order reaction?

Choose the correct answer. a) The equation for t_{1/2} of first order reaction is i) t_{1/2}=0.693 / (K) ii) t_{1/2}=[A_{o]/2_{K}]

On introducing a catalyst at 500 K, the rate of a first order reaction increases by 1.718 times. The activation energy in the presence of catalyst is 6.05 kJ mol^(-1) . The slope of the plot of In k (sec^(-1)) against 1/T in the absence of catalyst is:

Unit of rate constant (k) of a reaction depends on the order pf the reaction Value of 'k' of two reaction are given below. Find the order of each reaction k=5xx10^(-3)molL^(-1)s^(-1)

Write the relation between half life t_(1/2) and rate constant (k)of a first order reaction .
