(b)(i) State Le Chatelier's principle.

(ii) Suggest three conditions necessary for maximum yield of A\(_2\)B in the reaction represented by the following equation 2A\(_{2(g)}\) + B\(_{2(g)}\) \(\rightleftharpoons\) 2A\(_2\)B\(_{(g)}\) \(\Delta\)H = xkj.

(iii) Write an expression for the equilibrium constant of the reaction in (b)(ii) above.

(c)(i) Give the reason why a log of wood of a given mass does not burn out as quickly as sawdust of the same mass, under the same conditions.

(iii) List two examples of chemical reactions that are catalyzed by light
