Explanation :
1) this is endothermic reaction . so temperature increases , then the reaction shift ot right. so purple color increase.
2) if catalyst is added , then no effect on equilibrium
3) if more NH3 is added , then reaction shift to right. so purple color increase.
4) no pressure effect on equilibrium. because there is no gases
