Catalysts lower the activation energy of a chemical reaction. Activation energy is the energy required for a reaction to start or proceed. By lowering the activation energy, catalysts make it easier for the reactants to overcome the energy barrier and initiate the reaction. This allows the reaction to occur more quickly or at lower temperatures than it would without a catalyst. In other words, catalysts provide an alternative reaction pathway with a lower activation energy, making the reaction more favorable.

The forward arrow in a chemical equation represents the direction in which the reaction proceeds. It does not indicate the speed of the reaction or whether the reaction is reversible or not.
Answered by GPT 3.5
The forward arrow in a chemical equation does not indicate whether the reaction is fast or slow. The speed of the reaction can vary and is not specified by the arrow.
Answered by GPT 3.5
Yes, "the reaction yields something" is a correct interpretation of the forward arrow in a chemical equation. The arrow is used to indicate the product(s) that are formed as a result of the reaction. It shows what the reactants are transforming into or producing. So, the reaction on the left side of the arrow yields the product(s) on the right side of the arrow.

Photosynthesis is an endothermic reaction. This means that it requires energy input in the form of sunlight to proceed. Specifically, photosynthesis is a process in which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose and oxygen.
Answered by GPT 3.5
Photosynthesis requires light energy. Plants, algae, and some bacteria use light energy from the sun to power the conversion of carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of these organisms and is facilitated by chlorophyll, a pigment that absorbs light energy.
