For a first-order reaction, the half-life period is independent of:
A solution contains 0.01 M Ag+ and 0.01 M Ba2+. Potassium chromate (K2CrO4) is slowly added. Ksp of Ag2CrO4 = 1.1 x 10^-12 and Ksp of BaCrO4 = 1.2 x 10^-10. Which salt precipitates first and at what [CrO4 2-]?
The enthalpy of combustion of methane is −890 kJ/mol. The heat released when 8.0 g of CH₄ is completely burned is:
The enthalpy of formation of NH₃ from N₂ and H₂ is −92 kJ/mol. The enthalpy change when 8.5 g of NH₃ is formed from its elements is: (Molar mass of NH₃ = 17 g/mol)
The solubility of AgCl (Ksp = 1.8 × 10⁻¹⁰) in 0.1 M NH₃ solution is approximately given that Ag⁺ forms [Ag(NH₃)₂]⁺ with Kf = 1.7 × 10⁷:
Which of the following statements about enzyme catalysis is CORRECT?
The half-life of a first-order reaction is 69.3 seconds. The rate constant of the reaction is:
The rate constant of a first-order reaction is 6.93 × 10⁻³ s⁻¹. The half-life of the reaction is: (log 2 = 0.301)
