The use of powder calcium carbonate will give a larger surface area so that the rate of reaction will increase because the collision, where two different molecules bump into each other, has to happen at the liquid solid interface if the liquid solid interface is larger then more collisions will take place in a period of time making the reaction faster...

If chips of calcium carbonate are used the opposite would happen, there would be a smaller liquid solid interface and therefore a smaller amount of collisions will take place in the same period of time. By increasing the temperature you are adding more energy to the molecules. When the molecules have more energy they will be moving a lot more giving the opportunity for more collisions to take place, and more molecule will have sufficient energy for the reaction to take place, making the rate of reaction faster...
