A) \[{{x}_{1}}+{{x}_{2}}-{{x}_{3}}\]
B) \[{{x}_{3}}-{{x}_{1}}-{{x}_{2}}\]
C) \[{{x}_{1}}-{{x}_{2}}-{{x}_{3}}\]
D) \[{{x}_{3}}-{{x}_{1}}-{{x}_{2}}\]
Correct Answer: A
Solution :
[a] \[\Delta H{}^\circ =\Delta H_{f}^{{}^\circ }\](products)\[-\Delta H_{f}^{{}^\circ }\] (reactants) \[\Delta H{}^\circ =\Delta H_{f}^{{}^\circ }(HS)+\Delta H_{f}^{{}^\circ }(H)-\Delta H_{f}^{{}^\circ }({{H}_{2}}S)\] \[{{x}_{1}}=x\,(?)+{{x}_{3}}-{{x}_{2}}\] \[\therefore \]\[x=({{x}_{1}}+{{x}_{2}}-{{x}_{3}})\]You need to login to perform this action.
