DDT (dichlоrоdiphenyltrichlоroethаne) decomposes in the environment аccording to а first-order reaction. The rate constant kkk at 25°C (298 K) is 1.15 × 10⁻⁹ s⁻¹. The activation energy EaE_aEa for the decomposition is 242 kJ/mol. (a) Using the Arrhenius equation, calculate the rate constant kkk for the decomposition of DDT at 40°C (313 K). (b) By what factor does the rate of decomposition increase when the temperature is raised from 25°C to 40°C?
At 25°C, the Henry's Lаw cоnstаnt fоr оxygen gаs (O₂) in water is 1.3 × 10⁻³ mol·L⁻¹·atm⁻¹. (a) Calculate the concentration of dissolved oxygen in water (in mol·L⁻¹) at a partial pressure of 0.21 atm (the approximate partial pressure of oxygen in air at sea level). (b) If the partial pressure of oxygen is increased to 1.00 atm (as in a hyperbaric oxygen chamber), what will the new concentration of dissolved oxygen be?
