Answer the following questions based on the reaction below. At 210 K, the rate constant for this reaction is 3.58 /M s and at 624 K the rate constant is 5.32 times 105/M s. 2(1,3-butadiene) rightarrow 4-vinylcyclohexcnc Determine the activation energy (EA) (in kJ/mol) for this reaction. Report your answer to three significant figures in scientific notation. Determine the pre-exponential factor, A (in /M s) for this reaction. Report your answer to three significant figures in scientific notation (Please carry all the digits for EA calculated in part 1). 3. Determine the rate constant (in /M s) for this reaction at 1001 K. Report your answer to three significant figures in scientific notation (Please carry all the digits for A calculated in part 2).Explanation / Answer
K= Ae^-(Ea/RT)
so
lnK2/K1= Ea/R(1/T1- 1/T2)
thus ln(5.32*10^5/3.58)= Ea/8.31( 1/210-1/624)
Ea=31324 J/m
= 31.3 KJ/mol
2).K= Ae^-(Ea/RT)
thus
3.58= A e^-(31324/8.314*210)
A= 2.21*10^8 /Ms
3).lnK2/K1= Ea/R(1/T1- 1/T2)
we get
ln(K2/3.58)=31324/8.31(1/210-1/1001)
thus K2=5.175*10^6/ Ms
