A reaction was found to be spontaneous at temperatures above 1500 K, and nonspontaneous below 1500 K. If its enthalpy is +852 kJ/mol, what is its entropy?​

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
