NEED HELP ASAP! The gas phase reaction

2 N2O5(g) → 4 NO2(g) + O2(g)

has an activation energy of 103 kJ/mol, and the first order rate constant is
8.00×10-2 min-1 at 327 K. What is the rate constant at 367 K?

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
