Question

The activation energy for a reaction is found to be 80kJmol¹. Calculaye the temperature at which the rate will be ten times that at 0°C. (3 marks)​

Answer 1

Answer: Chain of thought reasoning: 1. Plan of action: We can use the Arrhenius Equation to solve this problem, as it relates the rate of a chemical reaction to the temperature. 2. Apply the equation: k = A e^(-E_a/RT) 3. Rearrange to isolate the Temperature: T = (E_a/R)*ln(k/A) 4. Insert data for the equation: T = (80,000 Jmol⁻¹/8314 Jmol⁻¹K⁻¹)*ln(10/A) 5. Solve for T: T = 3,008.34 K (or 2,735.19°C)
