Consider the following reaction:

3CH4(g)?C3H8(g)+2H2(g)

You may want to reference (Pages 832 - 835) Section19.7 and (Pages 1088 - 1091) Appendix C while completingthis problem.

Part A:

Using data from Appendix C in the textbook,calculate ?G? at 298 K.

Express the Gibbs free energy in kilojoules to one decimalplace.

?G?= ____ kJ

Part B.

Calculate

Calculate ?G at 298 K if the reactionmixture consists of 40 atm of CH4,0.013 atm of C3H8, and2.1×10^?2 atm of H2.

Express the Gibbs free energy in kilojoules to two significantdigits.
