Question

chemistry question

Answer 1

i know and i already solved it but what is k i don;t know

Answer 2

The k here is the rate constant. But I don't know what K and T are.

Following Arrhenius equation K is presumably Ea/R while T is temperature. Note that Ea is in units of joule/mole and R is the gas constant.

Answer 3

This is basically testing your algebra.
To solve for E\(_a\), you should get:
RT(ln(K)-ln(A))=E\(_a\)

Answer 4

Which is essntially \(\Delta\)G - RTln(A)
