Answer:

NH3 has higher critical temperature than

CO2, Hence, NH3 has greater intermolecular forces of attraction and hence will be adsorbed more readily.

Concept: Adsorption process.To find: which gas (SO2 or H2)will be adsorbed more readily on the surface of charcoala and the reason behind it.Answer: SO2 gas.Explanation:A gas which gets easily liquified, is most readily adsorbed.And lesser the value of critical temperature of a gas, lesser will be the adsorption.Hence H2 with critical temperature 33k shows least adsorption and SO2 gas with critical temperature 630k adsorb more readily on the surface of charcoal.#SPJ3

Answer:

पूर्ति का नियम माँग के नियम के विपरीत है। जैसे कि माँग के नियम में कीमत बढऩे से माँग घटती है और कीमत घटने पर माँग बढ़ती है। ... दूसरे शब्दों में अन्य बातें समान रहने पर किसी वस्तु की पूर्ति के बढ़ने की प्रवृत्ति तब होती है जब उस वस्तु की कीमत में वृद्धि होती है और पूर्ति में कमी तब होती है, जब वस्तु की कीमत में कमी आती है।
