Answer #1

Taking the log of each side

In k =In(Ae-Ea/Rt) =In A+ In(e-Ea/Rt) =In A + (-Ea/Rt)

In k=--Ea/Rt + In A

Which can be vuewvi as

In k-(-Ea/R) (1/T) + In A

This is in the form y=mx+b where x=1/T and y= In k

So the slope of the straight line is

-Ea/R answer D

    ln(k) = -E_a/R 1/T + ln(A) A plot of ln (k)versus 1/T result in a straight line with a slope = -E_a/R. The value of E_a can then be calculated using the value of R and to the slope of the line. This experiment uses the Arrhenius equation, which relates the temperature and specific reaction rate constant to determine the activation energy for the crystal violet reaction. The reaction will be performed at different temperatures. Once the order of reaction...

    To use the Arrhenius equation to calculate the activation energy. As temperature rises, the average kinetic energy of molecules increases. In a chemical reaction, this means that a higher percentage of the molecules possess the required activation energy, and the reaction goes faster. This relationship is shown by the Arrhenius equation k=Ae−Ea/RT where k is the rate constant, A is the frequency factor, Ea is the activation energy, R = 8.3145 J/(K⋅mol) is the gas constant, and T is the...
