modified arrhenius equation
What is modified Arrhenius concept?
To account for this behavior of H+, scientists can come up with the modified Arrhenius theory.
The modified Arrhenius theory proposes that acids are substances that dissociate to form hydronium (H3O+) ions, while bases are substances that dissociate to form hydroxide (OH-) ions.What is in Arrhenius equation?
The equation is commonly given in the form of an exponential function, k = Aexp(−E/RT), and it predicts that a small increase in reaction temperature will produce a marked increase in the magnitude of the reaction-rate constant.
"Linearized" Arrhenius Equation
For example, taking the logarithm of both sides yields the equation above in the form y=-mx+b.
Then, a plot of lnk vs. 1/T and all variables can be found.
This form of the Arrhenius equation makes it easy to determine the slope and y-intercept from an Arrhenius plot.
What is the rearranged Arrhenius equation?
Notice that when the Arrhenius equation is rearranged as above it is a linear equation with the form y = mx + b; y is ln(k), x is 1/T, and m is -Ea/R.
The activation energy for the reaction can be determined by finding the slope of the line.
