Chapter 13, Problem 13.72QP

Interpretation Introduction

Interpretation:

Form the given information, the surface area of the catalyst has to be calculated and from the two geometric configurations of the catalysts more effective one has to be identified. The total surface area of the sphere has to be calculated. Sometimes it is dangerous to work in grain elevators the reason behind this should be given.

Concept introduction:

• The radius of the sphere can be calculated by using the following formula.

$\text{V = }\frac{\text{4}}{\text{3}}{\text{πr}}^{\text{3}}$

• The surface are of the sphere can be calculated by using the following formula

${\text{area = 4πr}}^{\text{2}}$
