What is the value of the rate constant at 380 celsius given that the rate constant at 80 celsius is 7.2*10^-2s^-1© BrainMass Inc. brainmass.com October 24, 2018, 6:00 pm ad1c9bdddf
The variation of rate constant with temperature can be explained using the Arrhenius relationship
k = A exp(-Ea/RT)
T is the Temperature, meaured in kelvin. As a rule of thumb, a temperature increase of 10° causes a the reaction speed to double.
R is the gas constant.The value of the gas constant,R = 8.31JK-1mol-1.
Ea is the ...
The solution provides and easy to follow explanation of the concepts and gives all mathematical steps wherever necessary.
Activation Energy and the Arrhenius Equation
Given that the rate constant is 4.0×10^−4 at 25.0 degrees C and that the rate constant is 2.6×10^−3 at 42.4 degrees C, what is the activation energy in kilojoules per mole?View Full Posting Details
