H will definitely be positive because a bond is always more stable than no bond surely if it is a sigma bond.
For G you can't really know because you don't know how much energy is provided by the bond and if it outways the loss in disorder.
The reaction will become more spontaneous with a lower temperature because H tells you the reaction is exotherm
Answer:
Work done=50J
Heat removed=29J
Now
Hence the internal energy would decrease by 21J
Answer:
5.7 × 10⁻³
Explanation:
3.51 - 2.94 = 0.57
Don't change the scientific notation.
0.57 × 10⁻²
BUT
The "0" is not applicable so move the decimal point to the right by one and subtract the power by one.
5.7 × 10⁻²⁻¹ = 5.7 × 10⁻³
Confidence is best
