Question

Item 1 13 The reaction between iron and oxygen to form rust occurs spontaneously Part A Based on your expenence does this reaction occur rapidly? What does this imply about the relative magnitudes of the activation energy and G for the reaction? Explain. Drag the terms on the left to the appropriate blanks on the right to complete the sentences Reset Help small In the process of rust formation, G is because it is stated that the process is positive negative fast slow large spontaneous. Since rust formation is Eact is Submit y Answer Give Up Incorrect; Try Again; 4 attempts remaining You filled in 2 of 3 blanks incorrectly Continue

Explanation / Answer

The process of rust formation is spanteneous and hence for a spanteneous reaction the change in gibbs energy is negative. Since spanteneous process is exothermic so delta H is negative and also for this reaction delta S is positive and thus resulting in negative delta G for a spanteneous reaction

The Rust formation is very fast because of its spantenity

For any fast reaction the Activation energy is small. As activation energy is the energy barrier for a reaction to be carried out. if the Activation energy is large then we need to supply more energy to carry the reaction.
