Unformatted text preview: Taking the ln of both sides of the equation gives: ln k = ln A E a 1 R T which has the linear form y = b + mx, with y = ln k , b = ln A, m = E a /R and x = 1/T. A plot of ln k versus 1/T should be linear with slope = E a /R . While it is possible to calculate the values of E a and A from the slope and the yintercept of the plot, the linear form can be used directly to calculate k at any temperature because the slope and yintercept are known. In this case ln A = 31.3(E a /R) = 2.41E+4 K T = 619 K Substituting these into the linear equation gives ln k = 31.3 + (2.41E+4 )(1/ 619 ) = 7.63 k = e7.63 = 4.86E4 s1...
