Grade 12 solution
Real Time uy 12. A particular reaction requires 54 kJ mol to activate and is found to have a rate constant 1 -1 -1 -1 S S of 3.42 x 10-4 M¹s¹ at 155.85 °C. Predict the rate constant (in M¹ s¹ to two decimal places) if the temperature was increased to 460.85 °C. Approximately how much faster (to the nearest whole number) is the reaction predicted at 460.85 °C relative to 155.85 °C? A: 540 times faster
