Answer:
A substance that increases the hydronium ion concentration
Explanation:
Fluorine gas effuses 1.37 times faster than chlorine gas
calculation
Rate of F2/rate of Cl2 =√ molar mass Cl2 / molar mass F2
rate of F2/Rate of Cl2 = √1.868
rate of F2/rate of Cl2 =√ 71/38 = 1.37 times faster than chlorine
