Activation energy is the least amount of energy needed to start a chemical reaction. It is used to activate atoms or molecules in order for them to begin a chemical reaction.
Activation energy is really just the minimum amount of energy needed for a chemical reaction to occur. Without it, the energy will stay the same and the substance cannot undergo a chemical change. The thing to look at, I think, is the product of the reaction. For example, in a graph, two substances could have the same activation energy, but after the reaction the amount of energy in substance 1 could be extremely low and the amount of energy in substance 2 could be higher than the activation energy. In substance 1, evidence of an EXOTHERMIC reaction has occurred because the amount of energy in the original substance was lost indicating that it has released energy. Whereas in substance 2, when the amount of energy was higher than the activation energy, it is evident that an ENDOTHERMIC reaction has occurred because the amount of energy after the reaction is higher than it was before the reaction. This shows that substance 2 absorbedenergy making it endothermic. hope this helps!
The amount of energy necessary to cause a chemical reaction to occur is called activation energy.
The amount of chemical energy a substance has is determined by the types and arrangement of atoms and molecules in that substance. The energy is stored within the chemical bonds between these atoms and molecules. The strength of these bonds and the potential energy stored in them determine the amount of chemical energy.
A balanced equation indicates the chemical formulas for the substances involved in the reaction and the number of molecules or moles of each substance in the reaction. This enables a chemist to calculate the amount of each reactant needed to produce a desired quantity of product.
Mole is the the unit for amount of substance in SI.
This is usually referred to as the ACTUAL YIELD of that substance.

yes,as gibbs free energy depends on temp. ,its value for a fixed amount of a substance change,so chemical potential changes with reaction.
Items like H2O and CoC2 have a definite chemical composition, and require exact amount of particles to forma reaction. However; particles which are soluble in water do not have a definite chemical reaction.
In a chemical reaction the limitting reactant is also know as limiting reagent.it is the substance which is totally consumed when the chemical reaction is complete.the reacton can not proceed without it.

These coefficients show the number of molecules (and the amount of substance) involved in the chemical reaction.
A chemical reaction need an activation energy to start.
A mole is a unit that describes an amount of a substance that has 1 unit of Avogadro's number in it. Avogadro's number is 6.022 E23.
