Please give the definition of Le Chatilier's principle. Use this to explain what would happen if you increased the temperature of an equilibrium in which the forwards reaction is exothermic.

Le Chatilier's principle states that, if a change is made to a system at equilibrium, the position of equilibrium will shift to oppose that change. If you increase the temperature of a system where the forwa...

A curve has parametric equations -> x = 2cos(2t), y = 6sin(t). Find the gradient of the curve at t = π/3.

First we need to find the derivatives of x and y in terms of t. dx/dt can be found using the chain rule. Differentiating the inside of the bracket gives us 2. Multiplying the outside gives -2sin(2t) (Derivat...
