Answer to Question #198737 in General Chemistry for Erika Dumaraos

Question

Calculate the standard entropy values for the following reaction at 25°

1.)N2(g)+3H2(g)---> 2NH3(g)

2.)H2(g)+Cl2(g)-----> 2HCl(g)

3.)2CO2(g)+O2(g)--->2CO2(g)

4.)3O2(g)--->2O3(g)

5.)2NH3(g)+CO2(g)---->NH2CONH2(aw)H2O(I)

Answer 1

$1)Sº(N2)(g) = 191.6 J K^-1 mol^-1$

$2)Sº(H2)(g) = 130.6 J K^-1 mol^-1$

$3)Sº(CO2)(g) = 189.2 J K^-1 mol^-1$

$4)Sº(O2)(g) = 117.4 J K^-1 mol^-1$

$5)Sº(NH3)(g) = 193.3 J K^-1 mol^-1$
