Can a catalyst alone make a nonspontaneous reaction occur spontaneously Explain why or why not.?
No, a catalyst alone cannot make a nonspontaneous reaction occur spontaneously. A catalyst can only speed up the rate of a reaction by lowering the activation energy, but it cannot change the overall thermodynamics of the reaction. In order for a nonspontaneous reaction to occur spontaneously, the reaction must have a negative change in Gibbs free energy (G) value.

How the reaction principle works?
The reaction principle, as described by Newton's third law of motion, states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object exerts an equal force in the opposite direction. This principle helps to explain the interactions between objects in terms of forces.
Explain why action and reaction forces do not cancel out even though they have equal magnitude and act in opposite directions?
Action and reaction forces act on different objects, so they do not cancel out. Newton's Third Law states that for every action, there is an equal and opposite reaction. This means that the forces are exerted on different objects, resulting in motion or changes in motion.
Why action and reaction forces produce motion explain?
Action and reaction forces produce motion because for every action force there is an equal and opposite reaction force, as stated by Newton's third law of motion. These forces act on different objects, causing them to accelerate in opposite directions, thus producing motion. When the forces are unbalanced, motion occurs due to the resulting acceleration.
Energy is neither created nor destroyed in a chemical reaction Explain where the energy released or absorbed by the reactions comes from or goes to?
Energy released by a chemical reaction is released as heat to the surroundings thus rising the temperature of the room or lab etc where the reaction is taking place. Similarly, energy absorbed by endothermic is either supplied by external heating of reaction mixture over a flame or absorbed from surroundings.
Which law of motion is used to explain rocket propulsion?
The third law of motion, known as Newton's third law, is used to explain rocket propulsion. This law states that for every action, there is an equal and opposite reaction. In the case of a rocket, hot gases are expelled backward, causing the rocket to move forward in the opposite direction.
Explain how a catalyst aids chemical reaction to take place and identify the subsequent chemical changes in the reaction?
A catalyst provides an alternative pathway with lower activation energy for the reaction to proceed, allowing it to occur at a faster rate. This facilitates the formation of the products. In terms of chemical changes, the catalyst itself is not consumed or altered in the reaction, and the overall stoichiometry and composition of the reactants and products remain the same.
Can combination reaction be oxidation reaction Explain?
No
Why do tablets dissolve at differend speeds with differend temps of water?
First of all, I want to explain that the speed of reaction depends on several factors. They are: - Availability of a catalyst -Temperature of reactants -Pressure of the system -Surface area. If you increase the temperature, the speed of reaction will be higher. This is because more water molecules have more sufficient energy to cause a reaction whenever they react with the tablets.
How can you change the rate of chemical change in a substance?
This is a very vague question and would depend on the chemical that you are talking about. The easiest way I can think to explain it on a wide variety of chemicals is by using a catalyst (speeds up the process of a chemical reaction), or the use of an antagonist (Slows a chemical reaction). I hope this helps, but without any specific chemicals being named this is the best i can do. :) By heating we can change the rate of chemical change(reaction).
What is the freedle crafts alkyletion reaction explain?
The Friedel-Crafts alkylation reaction is an organic chemical reaction in which an alkyl group is introduced to an aromatic ring via the action of an alkyl halide in the presence of a strong Lewis acid catalyst, typically aluminum chloride (AlCl3). This electrophilic substitution reaction results in the formation of an alkyl-substituted aromatic compound. However, it has limitations, such as the potential for polysubstitution and rearrangement of the alkyl group, which can lead to undesired products. Additionally, the reaction may not work well with highly substituted aromatic compounds or those with electron-withdrawing groups.
How can you explain the role of oxygen in combustion?
Oxygen is the oxidant in this reaction.
Are you surprised at his reaction explain?
umm iguess?? if iknew who you were talking about first
What is neutrailization explain with an example?
neutrallization is a chemical reaction of acid and alkali
Explain why the process of preparing cyclohexene proceeded smoothly?
The process of preparing cyclohexene proceeded smoothly because the starting material, cyclohexanol, readily underwent a dehydration reaction in the presence of a suitable acid catalyst. The reaction conditions were controlled to favor the formation of cyclohexene with minimal side reactions, leading to a high yield of the desired product. Additionally, the purification steps ensured that the final product was obtained in its pure form.
What is the purpose of a equated?
A chemical equation lets humans explain a chemical reaction. When the same reaction occurs repeatedly, the equation serves to remind us of what happened in the reaction.
