CBSEENCH11006244

In the following changes, state whether order has increased or decreased and consequently by the direction of change of entropy of the system:

left parenthesis straight i right parenthesis space Cr to the power of 3 plus end exponent space plus space 6 straight H subscript 2 straight O left parenthesis aq right parenthesis space space rightwards arrow space space Cr left parenthesis straight H subscript 2 straight O right parenthesis subscript 6 superscript 3 plus end superscript

left parenthesis ii right parenthesis space CO subscript 2 plus straight H subscript 2 straight O space rightwards arrow from Photosynthesis to Light of space space Carbohydrates space plus space straight O subscript 2

left parenthesis iii right parenthesis space Proteins space left parenthesis helical space form right parenthesis space space rightwards arrow with denaturation on top space Proteins space
left parenthesis random space coil space form right parenthesis

left parenthesis iv right parenthesis space Normal space egg space rightwards arrow space space hard space boiled space egg.

Solution

(i) The order has increased, entropy decreases in the forward direction.
(ii) The order has increased, entropy decreases in the forward direction.
(iii) The order has increased entropy decreases in the forward direction.
(iv) The order has increased, entropy decreases in the forward direction.
[Hint. Boiled egg is solid and less disordered as an ordinary normal egg which is a liquid].
