Question

Which of the following statements is TRUE? Perpetual motion machines are a possibility in the near future. There is a 'heat tax' for every energy transaction. A spontaneous reaction is always a fast reaction. The entropy of a system always decreases for a spontaneous process. None of the above are true. Given the following equation, H_2 O(g) + CO(g) rightarrow H_2(g) + CO_2(g) Delta G degree_rxn = -28.6 kJ Calculate Delta G degree_rxn for the following reaction. 5 H_2 O(g) + 5 CO(g) rightarrow 5 H_2(g) + 5 CO_2(g) +143.0 kJ -28.6 kJ +5.72 kJ -5.72 kJ -143.0 kJ Give the name of the reaction that does not achieve the theoretical limits with respect to free energy in thermodynamics equilibrium reaction reverse reaction irreversible reaction forward reaction reversible reaction
