ANswer thsi using particle in a box model for conjugated pi systems. A model has 12 double bonds with carbon backbone of 2.4 x 10^-9 m. what js the energy and color of light absorbed to excite an electron to next lowest energy level? and with 10 double bonds?
this aprt of calculation seems wrong ΔG° = -RTln(K) =>-3.9 × 10^5 J/Mol. = - 8.314 J/K .Mol × 298K ln (K) By Solving K = 9.77× 10^68 I think it is (-3.9 × 10^5 J/Mol) = (- 8.314 J/K Mol × 298K x ln(K) ln (K)= (-3.9 × 10^5 J/Mol) / (-8.314 J/K Mol × 298) ln (K)= 157.4 K = e^157.4 K = 2.3 x 10^68 are you right or me
