Q24.69 P - Chemistry: Molecular Nature Of Matter And Change

Question

A steel part is treated to form some iron-59 . Oil used to lubricate the part emits298  particles (with the energy characteristic of  ${}^{\mathbf{\text{59}}}\mathbf{\text{Fe}}$) per minute per milliliter of oil. What other information would you need to calculate the rate of removal of the steel from the part during use?

Step-by-Step Solution

Answer

The volume of oil and the concentration of ${}^{59}\text{Fe}$  in the steel sample would be necessary

Step 1: Rate of a reaction

According to the rate law, the rate of a reaction depends on the concentration of the reactants raised to the powers of their coefficients.

 

Step 2: Explanation

In order to calculate the rate of removal of the steel from the part during use, we need to find the volume of oil and the concentration of 59 Fe in the steel sample.

Hence, it would be essential to know the amount of oil and the concentration of ${}^{59}\text{Fe}$ in the steel sample.
