Please answer 9 and 11 thank you
Consider the table of thermodynamic parameters shown in the table and the formation of methanol from carbon monoxide and hydrogen at 298K: CO(g) + 2H_2(g) rightarrow CH_3OH(g) What is Delta H degree for this reaction at 298K? +90.7 kJ/mol -90.7 kJ/mol +128.1 kJ/mol -128.2 kJ/mol What is Delta S degree for this reaction at 298K? +90.1 J/mol-K +221 J/mol-K -90.1 J/mol-K -221 J/mol-K -332 J/mol-K Based on the values you found for Delta H degree and Delta S degree above, this reaction is always spontaneous never spontaneous spontaneous only at low temperatures spontaneous only at high temperatures Is this reaction spontaneous (in the forwards direction) under standard conditions at 298K? Yes, because Delta G degree = -25 kJ/mol Yes, because Delta G degree = +25 kJ/mol No, because Delta G degree = -25 kJ/mol Yes, because Delta G degree = -29 kJ/mol No, because Delta G degree = -29 kJ/mol
