- im struggling in chemistry, only if you’re serious about it!

describe the progression of a reaction using the graph below. start with reactants and proceed through products. make sure you talk about the following terms: reactants, activation energy, transition state, and products. is this reaction exothermic or endothermic?

A reaction, such as this one, starts with a reactant. It needs to have activation energy in order to change to the product, as shown by the hump in the graph. At the top of the hump is the transition state. This is the point where, after enough energy, the reactant will turn into the product. This reaction is exothermic. Since the product has less energy than the reactant, it had to have released energy somehow, and that energy was released in the form of heat, which makes it exothermic. (Exothermic reactions release heat, vs. endothermic reactions which absorb heat).

Bonus: a catalyst can be used to lower the activation energy by giving the reaction a “kick start,” requiring less energy in the reaction for the reactant to turn into the product.

-Lemme know if I can do anything else!

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
