6. (a) Ethylene glycol (EG), CH2(OH)CH2(OH), is a common automobile antifreeze.
It is water soluble and fairly nonvolatile (b.pt. 197 °C; molar mass 62.01 g;).
Calculate the freezing point of a solution containing 651 g of this substance in
2505 g of water, K¢ of water is 1.86 °C/m).
(b) Would you keep this substance in your car radiator during the summer?
7. Giving reasons, predict whether the aqueous solutions of the following compounds are
acidic, basic, or neutral: (i) HCI, (ii) KBr, (iii) Ethyl alcohol & (iv) NH,OH.
8. The decomposition of ethane (C2H6) to methyl radicals (CH3"), shown below is a
first-order reaction with a rate constant of 5.36 × 10 s at 700 °C.
C2H6 (g) → 2 CH3* (g)
Calculate the half-life of the reaction in minutes.
