Question

There are several factors that affect the rate of a reaction. These factors include temperature, activation energy, steric factors (orientation). and also collision frequency. which changes with concentration and phase. All the factors that affect reaction rate can be summarized in an equation Part A A certain reaction has an activation energy of 68.0kJ/mol and a frequency factor of A1 = 7.90=10^12 M^-1 s^-1 . What is the rate constant. k, of this reaction at 30.0 degree C ? Express your answer with the appropriate units. Indicate the multiplication of units explicitly either with a multiplication dot (asterisk) or a dash. k= values Units The linear form of the Arrhenius equation The Arrhenius equation can be rearranged to a form that resembles the equation for a straight line: where y is in k, m is the slope or -Ea/R, x is and b is the y -intercept or In A. The linearity of this equation is illustrated graphically in the image.(Figure 1)

Explanation / Answer

K= Ae^(-Ea/RT)

K = 7.9 x 10^12 x e^ ( - 68 x 1000 / 8.314 x 303 )

K = 14.95

so the rate constant K = 14.95 M-1 S-1
