The rate of a chemical reaction is related to:_______
aalyn [17]

The correct answer for this question is activation energy, orientation, and frequency.

The rate of a chemical reaction is directly related to its activation energy because the higher the activation energy the lower is the rate of reaction as we know the reaction only proceed when the reactants have absorbed the enough heat energy to reach the transition state. Thus activation energy determines the rate of reaction.

The orientation of the particles is also very important as we know that the reaction between the two reactants only occur when they collide with proper orientation in time the greater the probability of the collision the greater is the rate of reaction and also the number of collisions also determines the rate of reaction.

The frequency is directly proportional to the rate of chemical reaction as the frequency of the collision increases the rate of the chemical reaction also increases.

Why do some atoms form positive ions and others form negative ions?
Scrat [10]
It is energetically favorable for all atoms to have a complete outer electron shell. Loosely, the atoms on the left hand side of the periodic table only have a few extra electrons in their outer shell so it is energetically favorable for them to lose them. The atoms on the right hand side of the periodic table almost have enough electrons in their outer shell and so they have a tendency to gain them. Once electrons have left an electron shell, an atom will have a positive charge because it has more protons (positive charges) than electrons (negative charges). Similarly, an electron which has gained electrons to complete its outer shell will have a negative charge because it now has more electrons (negative charge) than protons (positive charge).
