(c) : In Arrhenius equation, k = Ae–Ea/RT  k = rate constant, A = frequency factor T = temperature, R = gas constant, Ea = energy of activation. This equation can be used...

(b) The basic character decreases from NH3 to BiH3 . The basic nature is due to the presence of lone pair of electrons on the central atom. NH3  is the strongest electron pair...

1 moles of C2H6 contain = 6.022 x 1023 molecules  3 moles of C2H6 contain = 6.022 x 1023 x 3 = 1.0807 x 1024 molecules.

The energy differences between staggered and eclipsed forms of ethane is just 12.55 kj mol_1 which is easily met by collisions of the molecules at room temperature. Therefore, it is...
