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...

Determine the coordinates of all the stationary points of the function f(x) = (1/3)*x^3+x^2-3*x+1 and state whether they are a maximum or a minimum.

To find the answer you must first differentiate the function and set this equal to zero. This forms the quadratic equation x^2+2x-3=0 which can then be solved either by factorisation or by using the q...
