Water- roots and root hair absorb water from the soil by osmosis. Roots are long and have a large surface area. Roots have thousand of root hairs behind the root tip. Root hairs increase the surface area, ensure close contract with soil to increase rate of water uptake and help penetrate all of the soil.
Minerals- minerals occurs as ions dissolved in water in soil. These ions are absorbed …show more content…
Increasing the surface area of the solid increases the chances of collision taking place.
Imagine a reaction between magnesium metal and a dilute acid like hydrochloric acid. The reaction involves collision between magnesium atoms and hydrogen ions.
Increasing the number of collisions per second increases the rate of reaction.
Catalytic converters use metals like platinum, palladium and rhodium to convert poisonous compounds in vehicle exhausts into less harmful things. For example, a reaction which removes both carbon monoxide and an oxide of nitrogen is:
Because the exhaust gases are only in contact with the catalyst for a very short time, the reactions have to be very fast. The extremely expensive metals used as the catalyst are coated as a very thin layer onto a ceramic honeycomb structure to maximise the surface area.
The explanation
You are only going to get a reaction if the particles in the gas or liquid collide with the particles in the solid. Increasing the surface area of the solid increases the chances of collision taking place.
