How is surface area of the reactant affect the the rate of the reaction? |
|
Answer» Solution :(i)In HETEROGENEOUS reaction, the surface area of solid reactantsplay an important ROLE in deciding the RATE (ii)For a given mass of a reactant , when the practical size DECREASE surface area increase. Increase in surface area of reactant leads to more Collision per litre per second and hence the rate of reaction is increased (iii)For example, powered CALCIUM carbonate reacts much faster with dilute HCI then with the same mass of `CaCO_3` as marble |
