The activation energy for the reaction no2 (g )+ co (g) ⟶ no (g) + co2 (g) is ea = 218 kj/mol and the change in enthalpy for the reaction is δh = -252 kj/mol . what is the activation energy for the reverse reaction? enter your answer numerically and in terms of kj/mol.

Subduction zones occur on earth where dense oceanic crust dives under more buoyant continental crust. these boundaries are characterized by a deep ocean trench next to a high continental mountain range, large numbers of earthquakes and volcanoes. all of this is further evidence for the a) big bang theory b) origin of the species eliminate c theory of plate tectonics d theory of natural selection 4 sedimentary rocks found high in the himalayen mountain
