a) endothermic means it absorbs heat.
So if you increase T, by le chateliers principle, equilibrium shifts right to absorb the additional heat due to the increase in temp.

B) increase as equilibrium shift right to produce whatever is removed.

C) equilibrium shift left to compensate the reduction in the reactant on the left

Wahh. .. Thank youu ^_^

Hi Liah,

correction to 11(c)

Because NH4HS is a solid (which concentration remains the constant) which means the addition or removal of the solid DOES NOT shift the eqm.

By the way solids are not included in Kc or Kp expression

Oops yup. I’m sorry I didn’t take note of the phase.
