The addition of a increases the rate of reaction by providing an alternative pathway with a lower activation energy?
A catalyst, like enzymes.
A catalyst is a substance that lowers the activation energy for a reaction and allows the process to speed up. The catalyst does not react with the substance so that it is 'used up'; in other words, it's reusable and comes out of the reaction unchanged.

What is the effect of the addition of a catalyst on the rate of a chemical reaction?
A catalyst increases the rate of a chemical reaction by providing an alternative pathway with lower activation energy. This allows for more reactant molecules to overcome the energy barrier and form products more quickly, without being consumed in the process.
Which accounts for the increase in the rate of reaction when a catalyst is added to a reaction system. Does the entropy of the reaction increase?
When two molecules react with each other they must form a transition state. The higher the energy of the transition state the less likely it is for the two molecules to react with each other. Catalysts lower the energy of the transition state. This makes it more likely for molecules to react with one another, which speeds up the overall reaction. Entropy is unrelated. Reactions that break apart molecules increase entropy. Reactions that combine molecules together diminish entropy. Both types of reactions can be sped up by catalysts.
Why an addition reaction increases the saturation of a molecule?
An addition reaction increases the saturation of a molecule by converting double or triple bonds into single bonds, increasing the number of hydrogen atoms bound to the carbon atoms. This reduces the number of pi bonds and increases the number of sigma bonds, leading to a more saturated molecule.
What parameter involved in a chemical reaction will change with the addition of a catalyst?
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
Is it correct to say that the addition of salts to water will always increase the surface tension of water?
Yes, the addition of salts to water typically increases the surface tension of water. This is because the salts disrupt the hydrogen bonding within water molecules, leading to stronger water-water interactions at the surface, which increases surface tension.

How does the addition of catalyst affect the energy of activation of chemical reaction?
It lowers it, so the reaction is faster.

How did the addition of more weight affect the friction?
When the weight increases the frictional force also increases:)
What does the addition of salt do to the properties of the water?
It increases its boiling point and its density.
Describe the structure and function of enzymes?
Catalyst increases the rate of reaction without being consumed by it. In addition, while the catalysts lower the activation energy, it does not change the energies of the original reactants nor products. Rather, the reactant energy and the product energy remain the same and only the activation energy is altered.The key importance of activation energy is that collisions only result in a reaction if the particles collide with enough energy to get the reaction started. This minimum energy required is called the activation energy for the reaction.
Why addition reaction increases the saturation of a molecule?
Because the h2o level rises

What are the alternative start codons used in protein synthesis?
In addition to the commonly used start codon AUG, alternative start codons such as GUG and UUG can also initiate protein synthesis.

Why is alcoholism a health issue?
Alcohol abuse increases the risk of certain diseases in addition to accidents and deaths.
