Surface area effect on rate score

A solid reactant in a food-preservative investigation is crushed so the exposed surface-area score is \(6\). If rate score is \(3\times\) surface-area score, calculate the rate score. Use the diagram labels before choosing the numerical relationship. Enter the answer and choose the interpretation that matches the chemistry.
