Question

Use the data given to calculate the value of delta G rxn for the reaction at 25C
2C(graphite)+H2(g)--->C2H2(g)

C H2 C2H2
S(J K^-1 mol^-1)| 5.74 |130.68| 201.0
-------------------
delta H(kJ/mol) | 0 | 0 |-226.8

a.-291.4 kj
b.-244.3 Kj
c.-226.8 kj
d.-207.6 Kj
e.-64.6 Kj

Answer 1

Tables, spaces, and the like don't do well on the board. You need to find another format that doesn't require spaces or tables.

Answer 2

Use the data given to calculate the value of delta G rxn for the reaction at 25C
2C(graphite)+H2(g)--->C2H2(g)

C______H2_______C2H2___________________5.74| 130.68| 201.0 | S (JK^-1mol^-1)
_______________________________________
0 | 0 | -226.8|delta H(KJ/mol)

d.-207.6 Kj
e.-64.6 Kj

Answer 3

Thanks for trying but I don't see an improvement over the previous version.

Answer 4

I cant figure out how to do a table :(

Use the data given to calculate the value of delta G rxn for the reaction at 25C
2C(graphite)+H2(g)--->C2H2(g)


C= S(J K^-1) => 5.74 and delta H(kJ/mol)=>0

H2= S(J K^-1)=> 130.68 and delta H (kJ/mol)=>0

C2H2= S(J K^-1)=> 201.0 and delta H(kJ/mol)=> -226.8
