In theory, methane can be used to produce hydrogen gas by a process in which it decomposes to elemental carbon and hydrogen: CH4(g)C(s)+2H2(g) The carbon produced in the first step is then oxidized to CO2 C(s)+O2(g)CO2(g) The values for G are as follows: CH4(g)=50.8kJ/molC(s)=0kJ/molH2(g)=0kJ/molCO2=394.4kJ/molO2(g)=0kJ/mol a) Calculate the Gr+1o values for the above two reactions Grxn1o=Grxn2o= b) Calculate the value for Gcoupledo and indicate whether or not the coupled reaction is spontaneous. Grrn0 for the coupled reaction = The reaction is
