The same mass of large, medium and small marbles where reacted separately with diluted HCl. This is and exothermic reaction. Will the rise in temperature for each reaction differ? If yes than why?
The smallest marbles will give the highest rise in temperature, than the medium and lastly the largest marbles will give the lovest rise in temperature.
The smaller the beeds the larger the surface area that interacts with the diluted HCl, thus more energy is transferred into the water.
