For a first order reaction, the half-life period is
dependent on the square of the initial concentration
dependent on first power of initial concentration
dependent on the square root of initial concentration
independent on initial concentration
A radioactive isotope having t1/2 = 3 days was read after 12 days. If 3g of isotope is contained in container, the initial weight of isotope was
12g
24g
36g
48g
After how many seconds will the concentration of the reactant in a first order reaction be halved if the rate constant is 1.155 x 10-3 s-1?
600
100
60
10
In a multistep reaction, the overall rate of reaction is equal to the
rate of slowest step
rate of fastest step
average rate of various step
the rate of last step
