1.The radioactive isotope tritium decays with a first-order rate constant k of 0.056 year-1. What fraction of the tritium initially in a sample is still present 30 years later? 2.A boiled egg can be cooked at 100.00C in exactly 5 minutes. At an altitude of around 2000 m where the boiling point of water is 93.00C, it takes exactly 7.5 minutes to cook the egg to the same amount. What is the activation energy for the reaction involved when an egg is boiled? 3.Barbiturates are synthetic drugs used as sedatives and hypnotics. Barbital ( M = 184.2 g/mol) is one of the simplest of these drugs. What is the boiling point of a solution prepared by dissolving 42.5 g of barbital in 825 g of acetic acid? 4.Barbiturates are synthetic drugs used as sedatives and hypnotics.
