When a mixture of ethane and oxygen in the ratio 9:1 by volume is compressed to about 120 atm pressure and passed over copper tubes at 475K, ethyl alcohol is formed. When a manganese-based catalyst is used 100°C, ethane can be oxidized to ethanoic acid.

Write your name, Centre number and candidate number on the Answer Sheet in the spaces provided unless this has been done for you. 10 The value of the equilibrium constant, Kc, for the reaction to form ethyl ethanoate from ethanol and ethanoic acid is 4.0 at 60 °C.
The easiest way to balance any combustion equation is to first write the general form. In a combustion reaction the products are always carbon dioxide (CO2) and water But the rule is that coefficients have to be whole numbers. So multiple both sides by 2 to get the final balanced equation.

Before the invention of the internal combustion engine, the only successful human flights were in balloons filled with hot air or a gas like hydrogen which is "lighter than air". But balloons cannot be properly controlled in flight 1 . Not until man had invented a powered, "heavier than air" machine could...
