Answer:

Helium is a noble gas and shares many properties with the other noble gases in the last column.

Explanation:

got it right

also it is classified as a noble gas, and hydrogen is a nonmetal so obviously they don't fit together, as the group is for alkali metals which Helium obviously isn't.

The activation energy of a reaction is 56.9 kj/mol and the frequency factor is 1.5×1011/s. Part a calculate the rate constant of
Vanyuwa [196]

We will use Arrehenius equation

lnK = lnA  -( Ea / RT)

R = gas constant = 8.314 J / mol K

T = temperature = 25 C = 298 K

A = frequency factor

ln A = ln (1.5×10 ^11) = 25.73

Ea = activation energy = 56.9 kj/mol = 56900 J / mol

lnK = 25.73 - (56900 / 8.314 X 298) = 2.76

Taking antilog

K = 15.8
