" Higher order "(<3)" reactions are rare due to "

In a class room discussion about order and molecularity of a chemical reaction, Ramu argued that “there are reactions which appear to be of higher order but actually follow first order kinetics.List out any three Important differences between order and molecularity.

A diffraction grating used at normal incidence gives a line lamda_(1)=600Å in a certain order supermposed on another line lamda_(2)=450Å of the next higher order. If the angle of diffraction is 30^(@) how many lines are there in 1 cm of the grating.

When the temperature of a body increases from T to T+ DeltaT , its moment of inertia increases from I to I + DeltaI . If alpha is the coefficient of linear expansion of the material of the body, the (Delta I)/(I) is (neglect higher order of alpha )

Order 1 Higher degree |Geometrical| Orthogonal

Between O2 and, O_(2)^(+) which one has higher bond order?

Between O_(2) and O_(2)^(-) which one has higher bond order?

Higher the bond order greater is the
