Question

Given below is a list of chemical reactions. 1. Burning octane fuel 2. Forming rust in an iron pipe 3. Baking a cake 4. Cement hardening Which sequence ranks the chemical reactions in order from fastest to slowest? 4, 3, 2, 1 1, 3, 2, 4 3, 2, 1, 4 1, 3, 4, 2.

Answer 1

The speed of reaction from fastest to slowest has been 1, 3, 4, 2. Thus, option D is correct.

The chemical reaction has been given as the change in the composition of the reactants, with the formation of product.

Speed of Chemical reaction

The following chemical reactions rate has been given as:

1. Burning octane fuel: It has been the fastest reaction.
2. Forming rust in an iron pipe: It has been the slowest process and takes up to years.
3. Baking a cake: The reaction requires the time for up to 30-40 minutes.
4. Cement hardening: The reaction requires the time of a day or two.

Thus, the speed of reaction from fastest to slowest has been 1, 3, 4, 2. Thus, option D is correct.
