Astudent monitored the reaction rate of a 0.600m sucrose solution, at 25 oc, and determined that the reaction is first order with respect to sucrose. if at 25.0 oc it takes 3.33-hours for the concentration of the 0.600m solution to drop to 0.300m. how many hours are required for the concentration of the sucrose solution to drop to 10.0 % of its initial concentration.

11.06 hours are required

Explanation:

Because the reaction is first order with respect of sucrose, we can use the formula:

ln [A]ₓ = -k*t + ln[A]₀

Where [A]₀ is the initial concentration of sucrose, k is a constant and [A]ₓ is the concentration remaining after a time t.

Putting the data given by the exercise we can calculate k:

Now with k, we can calculate t when [A]ₓ = 0.600 * 10/100 = 0.060 M

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.
