For an endergonic reaction, the statement ΔG is positive is
the true statement. So the first option in the given question is the correct
option. Any reaction that requires energy to be absorbed is called an
endergonic reaction. For example, photosynthesis is a great example of
endergonic reaction. In photosynthesis sunlight is required to be absorbed to
complete the reaction. The sunlight acts as the energy required. This type of
reaction is never spontaneous, but requires external force to complete the reaction.
