Question

Butadiene reacts with itself to form a dimer with the formulaC8H12. the reaction is a second oreder in the C4H6. if the rate ata constant at a particular temperature is 4x10^-2 and the initialconcentration of C4H6 is 0.0200M what is its molarity after a reaction time on 1 hour? Butadiene reacts with itself to form a dimer with the formulaC8H12. the reaction is a second oreder in the C4H6. if the rate ata constant at a particular temperature is 4x10^-2 and the initialconcentration of C4H6 is 0.0200M what is its molarity after a reaction time on 1 hour?

Explanation / Answer

Given: [A]0 = 0.0200M            k = 4*10^-2             t = 1hour Given: [A]0 = 0.0200M            k = 4*10^-2             t = 1hour Fromula : 1/[A]0 - 1/[A] = kt so   [A] = [A]0 /{1+kt[A]0} where [A]0 , [A] are initial , finalconcentrations of the reactant. [A] = 0.0200M / {1+4*10^-2*1hour*0.0200M}
