H2(g) + F2(g)2HF(g) Using standard thermodynamic data at 298K, calculate the entropy change for the surroundings when 2.20 moles of H2(g) react at standard conditions. SĀ°surroundings = J/K
Answers: 1
for the surrounding when given amount of hydrogen gas is reacted is -31.02 J/K![\Delta S^o_{rxn}=\sum [n\times \Delta S^o_{(product)}]-\sum [n\times \Delta S^o_{(reactant)}]](/tpl/images/0531/3518/52737.png)
![\Delta S^o_{rxn}=[(2\times \Delta S^o_{(HF(g))})]-[(1\times \Delta S^o_{(H_2(g))})+(1\times \Delta S^o_{(F_2(g))})]](/tpl/images/0531/3518/0a21f.png)
![\Delta S^o_{rxn}=[(2\times (173.78))]-[(1\times (130.68))+(1\times (202.78))]\\\\\Delta S^o_{rxn}=14.1J/K](/tpl/images/0531/3518/7b4e1.png)
