molecule

The mass of molecule A is twice that of molecule B.The root mean square velocity of molecule A is twice that of molecule B. If two containers of equal volume have same numbe of molecules, the ratio of pressure P_(A) //P_(B) will be :

Assertion : Oxidation of one molecule of NADH gives rise to 3 molecules of ATP and that of one molecule of FADH_(2) produces 2 molecules of ATP Reason : The number of ATP molecules synthesised depends on the nature of the electron donor.

The mass of an oxygen molecule is about 16 times that of a hydrogen molecule. At room temperature the 'rms' speed of oxygen molecules is v. The 'rms' speed of oxygen molecules is v. the 'rms' speed of the hydrogen molecules at the same temperature will be
