Help with #8
Like aforementioned, radioactive decay is a first order reaction. Potassium-40, which has a half- life of 1.3 billion years, would take billions of years to decay. What is the time required for 45% of potassium-40 to decay? Activation Energy and Temperature Dependance 7.) If a reaction has a rate constant K₁ of 1.2x10-5 s¹ at 20°C and 9.76x10-5 s-¹ at 30°C, what is the activation energy of the reaction? 8. Calculate the rate constant at 15°C for the hydrolysis of ATP given that it's equal to 3.0 x 10³ M-¹s-¹ at 45°C. The Ea= 49 kJ/mol 9. The formation of glucose from carbon dioxide will take millions of years, but can happen in minutes due to an enzyme called RuBisCO. How do enzymes increase the rates of reactions?
