Entropy is a measure of the disorder or randomness of a system. When the two gases mix, the number of microstates (possible arrangements of molecules) increases, leading to greater disorder and higher entropy.
So, the correct answer is:
B. increase
the answer remains A bcs 1 mole of Ammonia will occupy the same space with 1mole of nitrogen.And in this question,the bulbs are of equal volume.this implies that the number of moles of ammonia and nitrogen are the same in each bulb,so is their mole to volume ratio.if the two bulbs are connected,the mole to volume ratio still remains unchanged .
just imagine class A has 50 students,and a space of 100cm3,then class B has 50students with the same space as class A(100cm3)
if you combine both classes,the space occupied per student wont still change.
answer is A
The answer is C
The entropy in a mixture of gases is likely to decrease because heat will be evolved if heat is evolved there is a decrease in entropy.
