The value of ∆G for a chemical reaction is +423 kJ. Which of the following best describes how this reaction will proceed in an organism? The reaction is non-spontaneous and requires energy to proceed.
The reaction is non-spontaneous and results in an increase in entropy.
The reaction is spontaneous and causes a decrease in entropy.
The reaction is spontaneous and gives off energy to the surroundings.

answer; i believe the correct answer to the above question is ( friction)

1)

i))the process of preparing food by green plants in the presence of sunlight is called photosynthesis.

ii) leaf is the site for photosynthesis.

iii) it takes place as,

6h2o+6co2=c6h12o6+602

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
