`"e"^((-"E"_"a")/(920 " R"))`
`10^((-"E"_"a")/(2.303 " R"))`
`10^((-"E"_"a")/(921.2 " R"))`

उत्तर
For the decomposition of hydrogen iodide at 127°C, the fraction of molecules having energy equal to or greater than activation energy can be given as `underline(10^((-"E"_"a")/(921.2 " R")))`.
Explanation:
Fraction of molecules = `"e"^((- "E"_a)/(10^(2.303 " RT")))`
`= 10^((-"E"_a)/(2.303 xx "R" xx 400))`
`= 10^((- "E"_"a")/(921.2 " R"))`
