Answer all 3 parts correctly and I will give you a Brainliest, 5-star rating, and thanks on question and profile

Kc = 0.040 for the system below at 450oc. if a reaction is initiated with 0.40 mole of cl2 and 0.40 mole of pcl3 in a 2.0 liter container, what is the equilibrium concentration of cl2 in the same system? pcl5(g) ⇄ pcl3(g) + cl2(g)

If 3 moles of a compound use 24 j of energy in a reaction, what is the a hreaction in j/mol?

In an exothermic reaction, energy may be released to the surroundings in the form of question 4 options: heat light thermal all of the above
