`H_(2)O` and O-atom react in upper atmosphere bimolecularly to form two OH radicals. `

Water and oxygen atoms react in upper atmospheric level bimolecularly to form two OH radicals having heat of reaction 72 kJ at 400 K and energy of activation being 77 kJ mol^(-1) . Calculate the E_(a) for bimolecular combination of two OH radicals to form H_(2)O and O -atom.

In gaseous reactions important for understanding of the upper atmosphere H_(2)O and O react bimolecularly to form two OH radicals. Delta H for this reaction is 72kJ/mol at 500 K and E_(a) = 77 kJ//mol , then E_(a) for two bimolecular recombination of 2OH radicals to form H_(2)O & O is

In gaseous reaction, important for the understanding of the upper atmosphere H_(2)O and O react bimolecularly to from two OH readicals. DeltaH for this reaction is 72 kJ at 500 K and E_(a) is 77 kJ "mol"^(-1) , then E_(a) for the bimolecular recombination of two OH readicals to form H_(2)O and O is :

There is formation of H_(2)O_(2) in the upper atomsphere. H_(2)O + O rarr 2OH rarr H_(2)O_(2) Delta H = 72 kJ mol^(-1) , E_(a) = 77 kJ mol^(-1) What will be the E_(a) for bimolecular recombination of two OH radicals to form H_(2)O and O in kJ.

The formation of O_3 in upper part of atmosphere is catalyzed by

H_(2)O_(2) on reacting with ethene gives
