Consider the system at equilibrium: `NH_(4)HS(s) hArr NH_(3)(g)+H_(2)S(g)" "DeltaHgt0`
Factors which favour the formation of more `H_(2)S(g)` include which of the following?
(P) adding a small amount of `NH_(4)HS(s)` at constant volume
(Q) increasing the pressure at constant temperature
(R) increasing the temperature at constant pressure
A. P only
B. R only
C. P and Q only
D. P and R only
