WebApr 16, 2024 · So, when data is taken on the rate of a chemical reaction, a plot of ln(k) versus 1/T produces a straight line. The gradient or slope of the line and its intercept can be used to determine the exponential factor A and the activation energy E a. This is a common experiment when studying chemical kinetics. WebThe activation energy is the amount of energy required to have the reaction occur. If you have more kinetic energy, that wouldn't affect activation energy. They are independent. Imagine climbing up a slide. If you climb up the slide faster, that does not make the slide get shorter. Hope this helped. :D 3 comments ( 4 votes) JacobELloyd 8 years ago WebAug 31, 2024 · How do you calculate the activation energy barrier? August 31, 2024 by Alexander Johnson Step 1: Convert temperatures from degrees Celsius to Kelvin. T = degrees Celsius + 273.15. T1 = 3 + 273.15. Step 2 – Find Ea ln (k2/k1) = Ea/R x (1/T1 – 1/T2) Answer: The activation energy for this reaction is 4.59 x 104 J/mol or 45.9 kJ/mol. dragon scale code shortest answer wins roblox
