In this experiment, the reaction between (D)-(–)-carvone and NaOH, H2O2 in MeOH was stirred at 0 °C for a short period of time, and then at room temperature for another 20 minutes. However, if you were to heat the reaction mixture to 70 °C for 2–3 days, a new product starts to form. Draw the expected new product.

I am having trouble solving this problem: The isomerization reaction shown here is temperature dependent. Given the starting material and the Kc, identify the number of molecules of reactant and product observed for each reaction. A=30 Kc: 5 Kc: .5 How would I set this up to solve the problem? I just need some direction I know Kc= B/A but it isn't working out
