Compared to `O_2`, diffusion rate of `CO_2` through the diffusion membrane per unit difference in partial pressure is much higher. Explain.

Give the partial pressure of O_2 in atmospheric air and alveolar air.

These questions consist of two statements each,printed as Assertion and Reason.While asnwering these questions you are required to chose any one of the following four responses. If both Assertion and Reason are true and Reason in correct explanation of Assertion. If both assertion and Reason are true but reason is not correct explanation of Assertion. If Assertion is true but Reason is false. If both Assertion and Reason are false. Assertion:In osmosis solvent moves through a semipermeable membrane from a place of lower diffusion pressure a place of higher diffusion pressure. Reason:It is due to migration of solvent from hypertonic solution to hypotonic solution through a semipermeter membrane.

the Number of atoms per unit cell in fcc and bcc unit cells are 4 and 2 respectively explain.

Compare and explain bond angles of H_2O and H_2S

From a certain apparatus, the diffusion rate of hydrogen has an average value of 28.7 cm^3 s^-1 . The diffusion of another gas under the same conditions is measured to have an average rate of 7.2 cm^3 s^-1 . Identify the gas

Read the following passage and answer the questions. Adsorption is surface phenomenon and its differ from absorption, Which occurs throughout the body of the substance which abosorbs. In physisorption, the attractive forces are mainly van der waals forces while in chemisorption actual bonding occuars between the particles of absorbent and absorbate. Generelly, easily liquifying gases are absorved more easily on the surface of a solid as compared to the gases which are liquified with difficulty. Adsorption increases with the increase in pressure and decreases as the temparature is increased. Arrange the following gases in the decreasing order of the ease with which they are adsorbed on charcoal. H_2 , CH_4 , CO_2 and NH_3

The time for a certain volume of a gas A to diffuse through a small hole is 2 minute If takes 5.65 minute for oxygen to diffuse under similar conditions Find the molecualr weight of A .

The decomposition of dimethyl ether leads to the formation of CH_4, H_2 and CO and the reaction rate is given by Rate = k [CH_3OCH_3]^(3/2) . The rate of reaction is followed by increase in pressure in a closed vessel, so the rate can also be expressed in terms of the partial pressure of dimethyl ether, i.e., Rate= k (P_(CH_3OCH_3 )^(3/2) If the pressure is measured in bar and time in minutes, then what are the units of rate and rate constants?

Consider the following reaction for 2NO_2(g) + F_2(g) rarr 2NO_2F(g) . The expression for the rate of reaction in terms of the rate of change of Partial pressures of reactant and product is/are
