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.

H_(2)O and O atom react in upper atmosphere bimolecularly to form two OH radicals. DeltaH for the reaction is 72 kJ at 500K and energy of activation is 77kJ mol^(-1) . Estimate E_(a) for bimolecular recombination of two OH radicals to form H_(2)O and O atom.

H_(2)O and O-atom react in upper atmosphere bimolecularly to form two OH radicals. DeltaH for the reaction is 72 kJ at 500 K and energy of activation is 77 kJ "mol"^(-1).E_(a) for bimolecular recombination of two OH radicals to form H_(2)O and O-atom, will be

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 :

In gaseous reactions important for-the understanding of the upper atmosphere H_2O and O react bimolecularly to form two OH radicals. DeltaH for this reaction is 72 kJ at 500 K and E_a is 77 kJ mol^-1 , then E_b for the bimolecular recombination of two OH radicals to form H_2O and O is::

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

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.
