Can you see if this is right   problem with last question

CH4(g) + H2O(g)CO(g) + 3H2(g)

H° = 206.1 kJ S° = 214.7 J/K at 298.15 K.

entropy change of UNIVERSE when 1.859 moles of CH4(g) react under standard conditions at 298.15  is -886.00

Is this reaction reactant or product favored under standard conditions? reactant

If the reaction is product favored, is it enthalpy favored, entropy favored, or favored by both enthalpy and entropy? If the reaction is reactant favored, choose ‘reactant favored’.

## For the reaction C(s) + H2O(g) = CO(g) + H2 (g) Science Assignment Help

For the reaction C(s) + H2O(g) = CO(g) + H2 (g)

H° = 131.3 kJ / mol and S° = 133.6 J / Kmol at 298 K. At temperatures greater than __________°C this reaction is spontaneous under standard conditions.

ΔG = ΔH – TΔS

=  131,300 – T(133.6)  (now not sure what do to – what happens to the minus

## Hypothetical defect on a enzyme in citric acid cycle Science Assignment Help

Explain where in the Citric Acid Cycle a hypothetical defect of an enzyme could occur that would decrease the overall ATP production.

Pick a specific enzyme in the citric acid cycle and discuss what would happen if it could not do its job – focusing on atp production. If this enzyme is defective, what happens to the levels of that enzyme’s product(s)? How does this impact the cycle as a whole? Can the cycle continue or does it stop? What happens to etc and at production.
