The rate of chemical reaction increases on increasing the surface area of reactants ,why? |
| Answer» Reactant\xa0concentration, the physical state of the reactants, and surface area,\xa0temperature, and the presence of a\xa0catalyst\xa0are the four main factors that affect reaction rate.\xa0Reaction rates\xa0can be affected by several factors, including\xa0concentration, temperature,\xa0surface area\xa0and presence of a catalyst. Increasing\xa0concentration\xa0increases the number of effective collisions.\xa0Increasing the surface area\xa0of a solid\xa0reactant\xa0exposes more of its particles to attack. This results in an\xa0increased\xa0chance of collisions between\xa0reactant\xa0particles, so there are more collisions in any given time and\xa0the rate\xa0of\xa0reaction increases. | |
