- 2HI (An elementary reaction)
If the volume of the container containing the gaseous mixture is increased to two times, then final rate of the
reaction
(1) Become four times
(2) Become th of the original rate
4
(3) Become 2 times
(4) Become
of the original rate​

Answer 1

Solution :

See the attachment for a labelled diagram of the circuit .

Here , we can clearly see that CE , EF , and FD are in series .

Equivalent resistance between them : 10 Ω + 20Ω + 20Ω = 50 Ω .

Now CD and the previous equivalent resistance are in parallel .

New Equivalent Resistance = 50×30/(50+30) = 1500/80 = 150/8 = 185 Ω .

This 185 Ω is parallel with the other two 10 Ω resistors .

Thus the final equivalent resistance becomes 205 Ω.

Answer - The equivalent resistance is 205 Ω .
