Nanoparticles Are Ideal for Chemical Reactions Because They Have a High

Short Answer

Nanoparticles are ideal for chemical reactions because they have a high surface-area-to-volume ratio. The surface-area-to-volume ratio for platinum-nickel nanoparticles in a hydrogen fuel cell is given by $\frac{3.464 x^{2}}{0.4714 x^{3}}$ , where $x$ is the side length. Simplify this ratio.
