Consider the following equilibrium: PC13(8) + Cl2(8) 2 PC1518)
If the volume of the system is decreased, how will the reaction rates in the new
equilibrium compare with the rates in the original equilibrium?

The answer is A and I don’t know why it isn’t B can someone explain

Amixture of gaseous sulfur dioxide and oxygen are added to a reaction vessel and heated to 1000 k where they react to form so3(g). if the vessel contains 0.669 atm so2(g), 0.395 atm o2(g), and 0.0851 atm so3(g) after the system has reached equilibrium, what is the equilibrium constant kp for the reaction: 2 so2(g) o2(g) ⇌ 2 so3(g)

In the following redox reaction which is the oxidizing agent and which is the reducing agent? alcl3 + na nacl + al

Place the elements below in order of decreasing ionization energy. aluminum(al) chlorine(cl) magnesium (mg) sulfur(s)
