Rust is an iron oxide, a usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances.
Explanation:
Ways to prevent rust are :
Paint It. Paint the bare metal with any durable acrylic paint. ...
Keep Moisture at Bay. Avoid contact with water or moisture. ...
Coat It With Oil. Use of oil or grease significantly reduces the chances of developing rust in iron. ...
Enzymes affect the rate of the reaction in both the forward and reverse directions; the reaction proceeds faster because less energy is required for molecules to react when they collide. Thus, the rate constant (k) increases. Figure 3: Lowering the Activation Energy of a Reaction by a Catalyst.
