How might you cause an edothermic chemical change to begin and keep going?

Answer 1

By supplying energy to it.

Explanation:

Since an endothermic reaction, by definition, NEEDS energy to go on, it will cool down (= taking heat energy from the reactants). It will stop itself as any reaction will slow down at lower(ing) temperatures.

So SUPPLY of heat is at least necessary to KEEP temperature at its minimum level of 'ongoing' reaction. (to: Chasity cordero)

Answer 2

In an endothermic chemical change, heat flows into the reaction (as opposed to exothermic reactions where the reaction gives off heat). To initiate the reaction only requires bringing the reactants into contact, but if it is too cold, the reaction will only proceed slowly. To accelerate the reaction and keep it going, there must be a constant supply of heat to the reactants. It is also necessary to constantly supply fresh reactants and preferably remove the reaction products - otherwise the reaction will approach thermodynamic equilibrium and essentially cease.

Answer 3

By heat , the more you add the more it keep going on

Answer 4

You add things in it or you can take heat from it' i.e. you have to cool it. this way you can take the reaction forward.

Answer 5

An endothermic reaction needs heat to keep it going … SO, heat the reactants.

Answer 6

You might cause an endothermic chemical change to begin and keep going by: adding thermal energy.

Answer 7

keep adding heat
