6.4*10^10 is the answer in scientific notation
<h2>The answer is option b "free energy is zero"</h2>
Explanation
- The reaction that has negative free energy are called exergonic reactions that means the reactants have more free energy than the product formed.
- The reaction that has positive free energy are called endergonic reactions that means the final state or the products formed have more free energy than the initial state or the reactants.
- The reaction that has zero free energy occurs when the free energy of both reactants and the products are same hence the rate of formation of products and reactants are equal.
- Therefore, when reactants and products are being formed at an equal rate the free energy is zero.
Answer:
It is the intermolecular forces acting between the molecules that cause attractions between them making them liquids or solids. The strength of Van der Waals forces depends primarily on the number of electrons in total in the molecule, so larger molecules will have higher boiling points.
Explanation:
Answer: II. The catalyst provides a new pathway in the reaction mechanism.
III. The catalyst speeds up the reaction.
Explanation:
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and more molecules convert to products.
The catalyst itself does not take part in the chemical reaction and gets regenerated as such at the end of the reaction without getting consumed.
The answer is D
Because the bread cannot go back to its previous state, and because a new substance was formed. :)
