Question

The rusting of iron is described by the reaction: 4 Fe(s) + 3 0_2(g) rightarrow 2 Fe_2o_3(s). The formation of rust on an exposed piece of iron typically takes several months Which of the following is NOT a reasonable assumption about this chemical reaction? The formation of rust has a low activation energy The formation of rust would occur faster in the warmer summer months than in the cooler winter months The formation of rust would occur more slowly at higher altitudes where the concentration of oxygen is lower The formation of rust has a low reaction rate

Explanation / Answer

Answer – We know the rusting of the iron is very slow process and it is occurring specially in the moisture, so rate of formation of rust is very slow. For the formation of rust, we need more oxygen. Since this reaction rate is too slow, so the energy of activation is very high. So according these condition answer for this is A) The formation of rust a low activation energy is not a reasonable assumption about this rust reaction.
