Consider the reaction. s⥫⥬ what effects are produced by an enzyme on the general reaction? the rate constant for the reverse reaction ) increases. δ for the reaction increases. the activation energy for the reaction is lowered. the concentration of the reactants is decreased. the formation of the transition state is promoted. the reaction equilibrium is shifted toward the products.

The correct answer is the activation energy for the reaction is lowered.

Explanation:

Enzymes are homogenous, thermolabile,biological catalyst which speed the rate of a reaction but itself remains unchanged throughout the reaction.

          Enzyme basically reduces the energy barrier also called activation energy and interact with the transition state of the reaction in a complementary fashion.

        Enzymes does not have any effect in the equilibrium of the reaction.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.

explanation:

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
