Please help I do not understand how to proceed with this. If someone could explain it and help that would be great

A chemical engineer is studying the following reaction:N2(g)+ 3H2(g) -+2 NH,(g)At the temperature the engineer picks, the equilibrium constant /, for this reaction is 0.0013The engineer charges ("fills") three reaction vessels with nitrogen and hydrogen, and lets the reaction begin. He then measures the composition of the mixtureinside each vessel from time to time. His first set of measurements are shown in the table below.Predict the changes in the compositions the engineer should expect next time he measures the compositions.reactionvesselcompoundpressureexpected change in pressureN244.91 atm@ 1 increase @ ! decrease(nochange)AH229.43 atm@ 1 increase @ ! decreaseo (nochange)NH41_06 atm@ 1 increase O ! decreaseo (nochange)N251.90 atm1 increase O ! decrease(nochange)BH 234.77 atm1 increase @ . decrease(nochange)NH.53.42 atm1 increase O ! decrease(nochange)N245.47 atm1 increase O ! decrease(nochange)C31_11 atm@ 1 increase @ . decrease(nochange)NH.39.94 atmO1 increase @ ! decrease(nochange)
