In the production of anhydrous copper sulphate (a reversible reaction), the forward reaction is an endothermic reaction. Explain the effect of increasing the temperature on the production of anhydrous copper sulphate.

By increasing the temperature, the reactant particles gain more energy. This has a two-fold effect. Firstly, the reactant particles gain more kinetic energy, therefore they start to travel faster, resulti...

the function f is such that f(x)=(2x-7)/4. Fnd f(-7) and the inverse of the function.

to find the first part we just need to plug in the value-7 in the expression for f replacing our independant value, x .f(-7)=(2*(-7)-7)/4 =(-14-7)/4 =-21/4to find the second part we need to interchange th...
