BIt is defined as complete loss of all protons from an atom.

CIt requires conversion of every substance into a noble gas.

DIt is independent of composition, structure, concentration and temperature in every case.

02Chemistry

Surface Chemistry Q02: A student is revising concept 1. Which correction is chemically sound?

AIt occurs only by peptide bond formation in proteins.

BIt is explained solely by colour change without particles or bonds.

CIt always has zero relation to electrons, ions or molecular structure.

DAdsorption is accumulation of species at a surface.

03Chemistry

Surface Chemistry Q03: In a standard exam item involving concept 1, which inference is valid?

AIt means all reactions become spontaneous without conditions.
