A sample of gas is held at constant temperature. If the volume of this sample of gas is doubled and the number of moles of this sample of gas is doubled, what happens to the pressure of the gas?
Select one:
a. The pressure is doubled.
b. The pressure is halved.
c. The pressure is quadrupled.
d. The pressure is quartered.
e. The pressure stays the same.

Is a logical series of steps

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
