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.

When chlorine is added to acetylene, 1, 1, 2, 2-tetrachloroethane is formed: 2cl2 (g) + c2h2 (g) → c2h4cl4 (l) how many liters o
Otrada [13]
Answer:
             20 L of Cl₂

Solution:

The reaction is as follow,

                                   H₂C₂  +  2 Cl₂     →      H₂C₂Cl₄

According to equation,

       167.84 g (1 mole) H₂C₂Cl₄ is produced by  =  44.8 L (2 mole) of Cl₂
So,
                 75 g of H₂C₂Cl₄ will be produced by  =  X L of Cl₂

Solving for X,
                      X  =  (44.8 L × 75 g) ÷ 167.84 g

                      X  =  20 L of Cl₂
