Question 4

4. For the simple decomposition reaction: AB(g)A(g)+B(g) rate =k[AB]2 and k=0.42M1s1 at 40C. a) How long will it take for [AB] to reach one-fifth of its initial concentration of 2.00M ? b) If Ea=75kJ, what is the value of "A" (the frequency factor in the basic Arrhenrus equation)? Do not worry about units. c) Write out the Basic Arrhenius Equation and explain how it takes into account factors that affect reaction rate
