Question
Methanol (CH3OH) is made industrially in two steps from CO and H2. It is so cheap to make that is is being considered for use as a precursor to hydrocarbon fuels, such as methane (CH4): Step 1: CO(g)+2H2(g)-->CH3OH(l) deltaS deg= -332J/K Step 2: CH3OH(l)-->CH4(g)+1/2O2(g) deltaS deg=162J/KCalculate deltaG deg in kilojoules for step 1
The change in enthalphy for the reaction is equal to to the change in enthalphy for the _______________ minus the change in enthalphy for the ______________ which is equal to ____________kJ (4 significant figures). The change in Gibb's free energy is __________kJ (3 significant figures). Methanol (CH3OH) is made industrially in two steps from CO and H2.

The change in enthalphy for the reaction is equal to to the change in enthalphy for the _______________ minus the change in enthalphy for the ______________ which is equal to ____________kJ (4 significant figures). The change in Gibb's free energy is __________kJ (3 significant figures).
Explanation / Answer
The change in enthalphy for the reaction is equal to to the change in enthalphy for the Product minus the change in enthalphy for the Rectant which is equal to -291.83 kJ (4 significant figures). The change in Gibb's free energy is 93107.33 kJ
