Question 1

Chlorine gas (Cl2\text{Cl}_2Cl2​) is reacted separately with sodium hydroxide under two different sets of conditions:

  1. With cold, dilute aqueous sodium hydroxide to produce sodium chloride (NaCl\text{NaCl}NaCl) and sodium chlorate(I).
  2. With hot, concentrated aqueous sodium hydroxide to produce sodium chloride (NaCl\text{NaCl}NaCl) and sodium chlorate(V).

For a fixed quantity of chlorine gas, what is the ratio of the moles of NaCl\text{NaCl}NaCl produced in the cold reaction to the moles of NaCl\text{NaCl}NaCl produced in the hot reaction?

A

1:51 : 51:5

B

3:53 : 53:5

C

5:35 : 35:3

D

1:11 : 11:1
