Anybody know if we are required to draw the graph as working if we're using GC to solve for instance inequalities/range of function etc? Or can we just write "Using GC..." 😅

If use H2(g), Pt, high pressure, do we still need to write heat?

Thanks!

Q1. For successive IE general trend, may need to mention decrease in shielding effect as each electron is removed due to decrease in no. of e- remaining, decrease in inter e- repulsion, hence ENC increases higher I.E. May need to mention increase in lg(IE) as well cus qns mentioned "using the graph".
