i'll wer in more details. 2H2S(g) +3O2 (g) ---> 2H2O (l) + 2SO2 (g) ︿︿ ｜｜ ｜｜ (1/4)S8(s) + 2H2(g) + 3O2(g) --- according to Hess law total enthalpy change is constant no matter which reaction pathway is taken. therefore enthalpy change ...
2H2S(g)+3O2(g)->2H2O(l)+2SO2(g) Calculate the standard enthalpy change for this reaction using standard enthalpies of formation. Okay so here is my work after using the standard enthalpy chart to determine the ∆Hf˚ 2H2S(g)=-20.5 kJ/mol 3O2(g)=0 kJ/mol 2H2O(l)=285.8 kJ...
1. Calculate the standard entropy Delta Srxn of the following reaction at 25 degrees C. The standard enthalpy reaction, Delta Hrxn, is -44 kJ mol-1. C2H4(g) + H2O(l) arrow C2H5OH(l) 2. Then, calculate Calculate the standard entrop...
