Answer #1

O2(g) +O(g)-----. O3(g)

heat or ehthaly of given reaction can be calculated by the formula

H reaction =  Hproducts - H reactants

standard enthalpy of formation of given are as fallows

O(g) = 249.170 kj/mol

O2(g) = zero , as it is in starard state and stable form

O3( g)= 142.67 kj/mol

now  Hreaction = 142.67+0 - 249.170 = -106. 5 kj/mol

The ozone layer is a protective layer around the Earth that absorbs UV radiations. Stratospheric ozone is depleted through the reaction of ozone, O3O3, with nitric oxide, NONO. The gaseous emissions from vehicles and industries are responsible for the rapid destruction of this layer. The destruction of the ozone by nitric oxide (NONO) is shown in the video. This is a two-step reaction, called a multistep reaction, involving a catalyst and an intermediate. Nitric oxide (NONO) enhances the reaction rate,...
