Power source (battery/energy) a copper/metal wire, and then a receiver
I believe it's B) it makes the water molecules bump into the solute more
Answer:B random mutations
Explanation: Because I took the test
The equilibrium constant of the reaction is 0.042.
The reaction equation is given as;
PCl5(g) ⇄ PCl3(g) + Cl2 (g)
Recall that this equation shows the decomposition of phosphorus pentachloride.
We have the following equilibrium concentrations;
[PCI5]= 0.0095 M
[PCI3] = 0.020
[CI2] = 0.020 M
The equilibrium constant, K is obtained from;
K = [PCI3] [CI2]/[PCI5]
K = [0.020]^2/[0.0095]
K = 0.042
