Consider the reaction: NH4NO3(aq)N2O(g)+2H2O(I) Using standard thermodynamic data at 298K, calculate the entropy change for the surroundings when 2.11 moles of NH4NO3 (aq) react at standard conditions. Ssurroundings=J/K Consider the reaction: 2CO2(g)+5H2(g)C2H2(g)+4H2O(g) Using standard thermodynamic data at 298K, calculate the entropy change for the surroundings when 1.85molesC of CO2(g) react at standard conditions. Ssurroundings=J/K For the reaction 2Fe(s)+3Cl2(g)2FeCl3(s) H=799kJ and S=440J/K G would be negative at temperatures (above, below) K. Enter above or below in the first box and enter the temperature in the second box. Assume that H and S are constant. 9 more group attempts remaining
