MF17083:For the following reaction find Kp at 25°C and indicate whether Kp should increase or decrease as the temperature rises. NH4HS(s) <===> H2S(g) + NH3(g); DH° = 83.47 kJ and DG° = 17.5 kJ at 25°C.
- A. B. C. D. E. F. Kp =
- A. B. C. D. E. F. Kp ________ as the temperature rises.
F. remains the same
I believe is Kp=0.0012 and Kp increases as the temperature rises can somebody verify that I am correct.
I found 8.6 x 10^-4 for Kp. I used
delta Go = -RT ln K.
delta Ho indicates the reaction is endothermic; therefore, an increase in T will move the reaction to the right, increaseing both pNH3 and pH2S so Kp will increase.
Check my thinking.
if a chemical has the pH of 2 what would be the [H
pH = - log(H^+)
