How does carbon dioxide concentration affect the rate of net photosynthesis?

As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. If carbon dioxide and light levels are high, but temperature is low, increasing temperature will have the greatest effect on reaching a higher rate of photosynthesis.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
