A catalyst will ALWAYS increase the reaction rate so C
Answer:
Ionic bonds form between two or more atoms by the transfer of 1 or more electrons between atoms. Electron transfer produces negative ions called anions and positive ions called cations. ... In forming an chemical bond, the sodium atom, which is electropositive, loses its negatron to chlorine.

Explanation:
When heat is absorbed by reactants in a chemical reaction then the reaction is known as endothermic reaction.
Whereas when heat is released by reactants in a chemical reaction then the reaction is known as exothermic reaction.
1. When 
is positive then it means heat is absorbed by reactants and reaction is endothermic.
2. When 
, this means energy of products is less than the energy of reactants. Therefore, it is exothermic in nature.
3. When energy is absorbed then reaction is endothermic.
4. When 
, this means energy of products is greater than the energy of reactants. Therefore, it is endothermic in nature.
5. When [tex]\Delta H is negative then it means heat is released by reactants and reaction is exothermic.
