A solid reactant is in the shape of a cube having side equal to 3 cm. The observed rate of reaction is .
If the cube is divided into smaller cubes having size 1 cm then the observed rate of reaction is .
If the cube is divided into smaller cubes having size 1.5 cm, then the observed rate of reaction is .
Which of the following correctly represents the relation between ?
In general, greater the surface area, greater is the rate of reaction
The total surface area will be greatest for the second case in which smaller cubes have size 1 cm followed by the third case in which the smaller cubes have size 1.5 cm
Hence, the correct order of rate of reactions is
Thus, the correct answer is Option (3)
