Help ASAP I Need It Now I Have To Write Similar Test Tmrw class=

Sagot :

A is Ea, which stands for activating energy. Energy is needed to get the reaction underway and Ea is the energy needed to “start” the reaction.

B is the temperature either released or absorbed.

The diagram shows that the reaction is exothermic based on the fact that the products energy is lower than the reactants. That is because energy (which is temperature in this case) is released during the process. If the reactants would have been lower than the products, the reaction would be endothermic.

Answer and explanation:

(c)

A represents the activation energy (the minimum amount of energy needed to start a reaction).

B represents the overall change in energy (the difference between the energy of the reactants and products).

(d)

The reaction profile diagram shows that the reaction is exothermic because the energy change is negative (the products have less energy than the reactants) which shows that energy is lost or given out to the surroundings.

(e)

HCl gas doesn't conduct electricity, but hydrochloric acid does because in HCl, there are hydrogen ions that are free to move so they can carry a charge.

Hope this helps!
