Chemical reactions move at different speeds. When a chemical reaction is moving at a slow speed, what can be done to speed up the reaction?

Enzymes may be defined as the bio catalyst that has the ability to increase the rate of a biochemical reaction occur in the living organism. The enzymes works at specific pH and temperature conditions only.

The enzymes are added to increase the rate of the reaction.Enzymes decreases the activation energy of the reaction by increasing the effective collision between the substrate.

Explanation:

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
