enthalpy change..please ten points?

Question

A certain reaction is spontaneous at 69degC. The enthalpy change for the reaction is 12 kJ/mol. Convert the temperature to K and then enthalpy change to J/mol

Answer 1

You really need to remember by heart:
(degree)C = K - 273.15, or K = (degree)C + 273.15
and
k means 1000, so:
1 kJ = 1000 J, 1km = 1000m, 1kV = 1000V, etc.
you should be able to do the work now.
