 Please answer but also explain all! Thank you!

The rate constant for a reaction is 1.5 times 10^-2 s^-1 at 734 K and 3.9 times 10^-2 s^-1 at 878 K. What is the activation energy? A) 440 kJ/mol B. 4300 kJ/mol C. 15 kJ/mol D. 36 kJ/mol E) This can’t be solved without knowing the frequency factor An unstable isotope of rhenium, ^191Re, has a half-life of 9.8 minutes and is a beta producer. What is the other product of the reaction? A) ^191Os B) ^191 W c) ^192 Pt D) ^190 W E) ^190Os The nuclide ^232_92 Th is radioactive. When one of these atoms decays, a series of alpha and beta – particle emissions occurs, taking the atom through many transformations to end up as an atom of ^_ Pb. How many alpha particles are emitted in converting ^23_92 Th into ^208_ Pb? A) 6 B) 8 C) 2 D) 214 E) 4
