Ethanol can be made from the reaction between ethene and water. The reaction is exothermic and occurs at a high temperature. Describe and explain the effect of raising the temperature on the rate of achievement of equilibrium and the equilibrium yield.

The rate of achievement of equilibrium increases. This can be explained by collision theory. Because the temperature is increases the reactants have more energy and therefor the collisions between them be...
