The p-V diagram of a gas undergoing a cyclic process (ABCDA) is shown in the graph where p is in units of `Nm^(-2)andV` in `cm^(3)`. Identify the incorrect statement .

A

a)0.4 J of works is done by the gas from A to B .

B

b)0.2 J of work is done on the gas from C and D.

C

c)No work is done by the gas from B to C .

D

d)Work is done by the gas in going from B to C and on the gas from D to A.

Text Solution

Verified by Experts

The area under p-V diagram = work done or W`=ADxxDC`
`=(2xx10^(5)-1xx10^(5))Nm^(-2)xx(4-2)xx10^(-6)m^(3)`
`=1xx10^(5)xx2xx10^(-6)J=0.2J`
Therefore , 0.2 J work is done by the gas in going from B to C and on the gas from D to A.

An ideal gas in a thermally insulated vessel at internal pressure =p_(1), volume =V_1, and absolute temp =T_1, expands irreversibly against zero external pressure, as shown in the below diagram. The final internal pressure volume and absolute temperature of the gas are p_(2), V_(2), and T_(2), respectively. For this expansion,

A gaseous compound A reacts by three independent first order processes (as shown in figure) with rate . constant 2 xx 10^(-3) , 3X10^(-3) and 1.93 xx10^(-3) sec^(-1) for products B, C and D respectively. If initially pure A was taken in a closed container with P = 8 atm, then the partial pressure of B (in atm) after 100 sec from start of experiment.
