Rhombic Sulphur entropy question? Although the equation said "S (Rhombic) + 3F2......", the data booklet suggests that Sulpher Rhombic generally consists as 8 Sulphur atoms. So do we multiply the molar entropy of S rhombic by 8?
I think you are supposed to. It makes sense that way. I didn't do it.

Where it was written that it consists of 8 Sulphur atoms ? And the data booklet says that the entropy in the table given applies to single atoms
But 1000/ t is directly proportional to initial rate of reaction while volume of IO3- is directly proportional to concentration. SO technically it's like a graph of rate against concentration. Hence, it's first order. My teacher confirmed it after seeing the paper.
It is not volume Vs rate, It was 1000/t (Rate) against volume. So it is first order. I showed the question to my teacher after the paper. He said it is first order.
It would be a curve if it is first order. I meant the same thing by saying volume vs rate. And your teacher is not supposed to read your question papers after the exam ??

Yeah I believe that as well, but he's referring that in the data booklet it says that this Sulphur atom consists of 8 sulphur atoms or something!
8 is the number of atoms per S molecule, if S exists as 8 atoms in equation, it multiplies by 8 to get that entropy, while if it exists as 1 atom, no multiplication is needed. Take hydrogen as example, booklet says it has 2 atoms per molecule, so it normally exists as H2 in equation, multiplication of 2 is needed. If it exists as (1/2)H2, mathematically it contains only one H atom, so no multiplication is needed. We can treat this S as (1/8)S8 alternatively, so for this, multiplication of 8 but also division of 8 is needed since it exists as 1 S atom, turning out no overall arithmetic. It's my opinion.

how did your graph look like? My teacher is allowed to see the extra papers that come along after the exam is over. Our papers are already sealed when he read it. So no prblem.
