Question

What cause chemical reactions to happen slowly

Answer 1

Explanation:

Chemical reactions can occur very slow or very fast depending on the following conditions:

• If the reactants are in solid phase, less surface area is exposed and the process proceeds very slowly. The exposed surface area is directly proportional to the rate of chemical reactions.
• If the concentration of the reactants are low. For gaseous systems, low pressure can inhibit the progress of chemical reactions.
• If the reaction is taking place at low temperature.
• No presence of a catalyst.
