I need help with Part B. I got Part A wrong Part A The activation energy of a certain reaction is 41.6 kJ/mol . At 20 ∘C , the rate constant is 0.0150s−1. At what temperature in degrees Celsius would this reaction go twice as fast? ANSWER IS T2= 32 Part B Given that the initial rate constant is 0.0150s−1 at an initial temperature of 20∘C , what would the rate constant be at a temperature of 120.∘C for the same...

please advise if calculations are correct. i got confused on
the signs when i got to 4 and for hess's law i plugged in the
equations given to me in the lab for the experiments and the delta
