WebFeb 2, 2024 · Using Equation 14.6.1 and the data from any row in Table 14.6.1, we can calculate the rate constant. Substituting values at time 10 min, for example, gives the following: rate = k[A]2 8.0 × 10 − 5 M/min = k(4.4 × 10 − 3 M)2 4.1 M − 1 ⋅ min − 1 = k. We can also determine the reaction order using the integrated rate law. WebIn the concentration range of 1 to $100 \mu \mathrm{g} / \mathrm{mL}$ P, phosphate suppresses the atomic absorption of $\mathrm{Ca}$ in a linear manner. The absorbance levels off, however, between 100 and $300 \mu g / \mathrm{mL}$ P. Explain. How can this effect be reduced?
