Is the following reaction spontaneous at 298 K? (Answer by calculating delta G)

patriot [66]

Answer:

The reaction H2O(g)+C(s) -> CO(g)+ H2(g) is NOT spontaneous because its ΔG = 91 kJ/moles

Explanation:

ΔG is calculated by ΔH - TΔS

ΔG = ΔH - TΔS

ΔG = 131.3 kJ/mole - 298K . 0,134kJ/mole K

ΔG = 91.068 kJ/moles

Be careful with the ΔS, because you have J, and in ΔH, you have kJ

never [62]

Answer:

Answer is explained in the explanation section below.

Explanation:

This question is requires the diagram, which I have drawn and it is attached in the attachment below. Please for this answer, refer to the diagram attached in the attachment below.

Referring to the diagram, attached. As we know that, Allylic secondary carbocations are more stable than Allylic tertiary carbocations.

Hence,

C2 will have a more positive charge since a tertiary carbocation (C2) is more stable than a secondary carbocation (C4). Therefore, the resonance structure will favor the positive charge at C2.
