Calculate the rate constant for the first-order decay of ^43K (t1/2 = 2.33 h)
A teacher developed a new chemical - NONDISTRACTUS, which allows students to focus in the classroom more and not be distracted by random events. For NONDISTRACTUS to be effective there must be a minimum concentration in the student's body of 2.00 x10-3 mol / L. If the concentration falls below this level, the students are faced with a 10 min nonproductive period where they cannot focus on anything. NONDISTRACTUS was found to undergo a very rapid first-order decay with a half-life (t½) in the bodies of students of 23 min. Based on this information:a) What is the rate law constant, k?b) If the student starts off with an initial concentration of 2.25 x 10-2 mol / L dose, how long will it be until the concentration is above the minimum 2.00 x 10-3 mol / L? Will it ensure that they are not distracted for the entire test?
I, used to treat thyroid cancer, decays with a first-order half-life of 6.99 × 105 s. How long does it take for the amount of isotope in a dose to decay to 19.0% of its initial value?
