Answer 1

Which of the following reactions results in an increase in entropy?

6CO2 (g) + 6H2O (l) yields C6H12O6 (s) + 6O2 (g)

N2O4 (g) yields 2NO2 (g)

H2 (g) + S (s) yields H2S (g)

2SO2 (g) + O2 (g) yields2SO3 (g)

Answer 2

Hmm i don't know that one

Answer 3

I think it is A

Answer 4

but I do not have a official answer for this one sadly

Answer 5

me neither im sorry :/

Answer 6

as in reason

Answer 7

first look at the states the products and reactants are in.

if it goes from solid -> liquid or gas
or liquid -> gas

entropy is increased

Answer 8

So would that mean A is correct?

Answer 9

no, you're actually decreasing entropy because you have liquid going to a solid

Answer 10

The correct answer is:

N2O4 (g) -> 2NO2 (g)

because you have 1 mol of N2O4 forming 2 moles of NO2

since you increased the number of gas particles, you increased the entropy

Answer 11

ohhhhh ok
