(a) The rate of reaction depends upon the surface area of reacting species. Powder form has more surface area than a peace of wood. Therefore pulverised wood burns faster than one gram piece of wood.
(b) An increase of 10K is not enough to double the kinetic energy because the molecular
speed is not going to change significantly whereas the rate of reaction doubles.
