What is the overall standard free-energy change for the following two reactions?

A + B-->2C äG = äG1
C + D-->E äG = äG2

a)äG1 + äG2
b)äG1 + 2äG2
c)äG2 – äG1
d)2äG2 – äG1
e)äG1äG22

  • Chemistry -

    A + B ==> 2C.....dG1
    2C + 2D ==> 2D...2dG2
    ---------------
    Adding gives me dG1 + 2dG2.
