Question
Which of the following statements is true for the following reaction?
NH4HS(s) NH3(g) + H2S(g); H° = 93 kJ
The reaction is spontaneous only at relatively high temperatures.
The reaction is spontaneous at all temperatures.
The reaction is at equilibrium under standard-state conditions.
The reaction is spontaneous only at relatively low temperatures.
The reaction is not spontaneous at any temperature.
A.The reaction is spontaneous only at relatively high temperatures.
B.The reaction is spontaneous at all temperatures.
C.The reaction is at equilibrium under standard-state conditions.
D.The reaction is spontaneous only at relatively low temperatures.
E.The reaction is not spontaneous at any temperature.
Explanation / Answer
answers :
A) The reaction is spontaneous only at relatively high temperatures
Explanation :
here H is positive and S is also positive. so
according to
G = H - T S
G is negative for very high temperatures. if G is negative that is spontenous reaction.
so in all of the options, only option A is correct
