Technically, it isn't "heat" that makes a chemical reaction happen. "Heat" is merely the flow of energy from one place to another. It is the energy itself that causes a reaction to occur. As an increase in temperature occurs, there is an increase in the energy in a group of molecules by making them mover around faster and bum into each other more. This energy is called "Activation energy", and is defined as the amount of energy required to make the reaction start and carry on spontaneously. Higher activation energy implies that the reactants need more energy to start than a reaction with a lower activation energy. With that being said, activation energy is the answer
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
The activation energy refers to a chemical reaction.
activation energy
The pathway with the greatest activation energy is often one that involves breaking strong chemical bonds or complex rearrangements, such as in nuclear reactions or some enzyme-catalyzed processes. These reactions require more energy input to initiate the reaction compared to other pathways with lower activation energies.

I think the term you're looking for might be "activation energy", but if so that's a pretty poor way of describing it, so I'm reluctant to say definitively that that's the answer (there really isn't an answer to the question as written).
catalyst
Yes, all chemical reactions require an initial input of energy, called activation energy, to start. This energy is needed to break the existing bonds in the reactant molecules and allow new bonds to form to produce the products. Once this energy barrier is overcome, the reaction can proceed on its own.
The chemical term activation energy is the amount of energy required for a chemical reaction to take place. For more information about different chemical contact a scientists or science professor in one's area.
Did you mean to ask "Can you go from activation energy tofree energy"?The answer might be found in looking at the definition of the coefficient of performance (COP), which states something like this:COP is the ratio of work or useful output (possibly free energy) to the amount of work or energy input (activation energy).If the COP is greater than one, then more energy is being produced than is required to produce it. One might argue that there is no such thing as free energy if you have to work for it.We are surrounded by free energy. Is the energy produced by a water wheel free? Is the energy produced by a wind turbine free? Is the electricity produced by a solar collector free? The energy is free for the collecting, but the method for collecting it has a cost of some kind.Check wikipedia for "trompe". There is a theory that the Giza pyramid has an underground structure that was designed as a trompe.
No, ions in solution do not need activation energy to react with one another. Since they are already in a dissociated state in solution, they can readily interact and form new compounds without the barrier of activation energy typically required for chemical reactions between neutral molecules.

The triple bond between the nitrogen atoms in nitrogen gas is very strong.it takes nearly a megajoule of energy to break apart one mole of nitrogen gas, This makes nitrogen very nearly inert at normal temperatures and pressures.
