Answer : The temperature in kelvins is, 
Explanation : Given,
= 178.5 KJ/mole = 178500 J/mole
= 161.0 J/mole.K
Gibbs–Helmholtz equation is :

As per question the reaction is spontaneous that means the value of
is negative or we can say that the value of
is less than zero.

The above expression will be:



Now put all the given values in this expression, we get :


Therefore, the temperature in kelvins is, 
The mass of the solid product of the reaction is determined by weighing.

Answer:
Total pressure increased
Explanation:
When gas C is added in the vessel then number of mole increases and number of collision depends on the number of molecules present in the vessel and on adding gas C ,mole also increases hence number of collision increases therefore pressure also increases because number of collision increases.
Total pressure increases.
