Question:
Sucrose hydrolyzes into glucose and fructose. The hydrolysis is a first order reaction. The half life for the hydrolysis of sucrose is 64.2 min at {eq}25 ^\circ C {/eq}. How many grams of sucrose in 1.25 L of a 0.389 M solution are hydrolyzed in 1.73 hrs?
Decay
To solve this problem, we will apply the formula for the first-order decay which is given by the formula below
$$\begin{align} \rm\ M &= \rm\ M_o e^{-kt}\\ \end{align} $$
where {eq}\rm\ M,M_o{/eq} are the final and original mass, k is the rate constant {eq}\rm\ k= \frac{\rm\ ln(2)}{\rm\ t}{/eq} and t is the time
