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,

Answer: Option B
Explanation: when strong acid react with strong base, the resulting solution is neutral as in the case of HCl and NaOH
HCl + NaOH —> NaCl + H2O
From the equation obtained, The salt ( NaCl) obtained is a normal salt which is neutral.
