Why does 1.00 gram of powered magnesium react faster than 1.00 gram of solid magnesium?

Ans

Higher surface area

Explanation:

The rate of chemical reacts are determined by temperature, agitation, and surface area. The more surface a substance is exposed to, the more it reacts.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

it's all four options.
