Which of the following will affect the rate of a chemical reaction? solution density solute mass solution volume solution temperature

solution temperature

Explanation:

The rate of chemical reaction depends on the temperature. The higher the temperature the greater is the kinetic energy of the particles. Particles at a higher energy collide with each other at a higher frequency. Collision of particles at a higher frequency and proper orientation is critical for accelerating a reaction.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
