Question

it takes time for prices of Shahabad tile to disappear in HCL but it's powder disappears rapidly​
sub science

Answer 1

$ANSWER :$

1. When HCl is added to Shahabad stone effervescence of CO2 is formed.

2. The CO2 effervescence is formed slowly with the pieces of Shahabad tiles while at the faster speed with the speed.

3. This is because the rate of a reaction depends upon the size of the particles of the reactants taking part in the reaction.

4. Smaller the size of the reactant particles , higher is the rate of reaction.

5. Hence, It takes time for pieces of Shahabad tile to disappear in HCl, but its powder disappears rapidly.

Thanks!!

Answer 2

(1) The rate of a reaction depends upon the size of the particles of the reactants taking part in the reaction. The smaller the size of the reactants particles, the more is their total surface area and the faster is the rate of reaction.

(2) In the reaction of dil. HCl with pieces of Shahabad tile, CO2 effervescence is formed and the tile disappears slowly. On the other hand, CO2 effervescence forms at faster rate with Shahabad tile powder and it disappears rapidly.

It takes time for pieces of Shahabad tile to disappear in HCl, but its powder disappears rapidly because in pieces of the tile, the surface atoms can only react with HCl but in powdered form all the atoms can react with HCl. This makes the difference in their reactivity.

Hope it helps...
