The final result of the dot product process can be: 1  Zero: we don't have any growth in the original direction. 2  Positive number: we have some growth in the original direction. 3  Negative number: we have negative (reverse) growth in the original direction.
number), and because R > 0 and T > 0, âG < 0 (a negative number). Therefore, if âG is a negative number, the reaction favors products. What must be true for âG to be negative and products to be favored? âG = âH â TâS a) âH is negative and âS is positive (then both contribute to making âG negative), for example: C 3 H 8 + 5 O 2! 3 CO
