How is activation energy related to bond energy?
If the bond dissociation energy for reactants is high then activation energy required for the reaction also will be high.
Why is the activation energy of an endothermic reaction is at least as large as its enthalpy?
In an endothermic reaction the energy of the products is higher than the energy of the reactants. The activation energy also is an energy increase. The activation energy must be at least as high as the products energy or the reaction would never take place. Thus, the activation energy must be at least as large as the enthalpy in an endothermic reaction.
How does temperature influence a chemical change?
Tempreture affects equilibrium in such a way dat when the tempreture of the reactants is high the rate of the foward reaction will be faster than the rate of backward reaction this is mainly due to the simple factor that when at high tempreture atom are at very high motion this there for increases there reactive factor .This also aplys to the products as they can also react to form reactants hence tempretures are kept constant or favouring the formation of desired products.
How do you draw enthalpy level diagrams?
its difficult to illustrate on this but basically the x axis is the progress of the reaction going from reactants to products the Y axis is the enthalpy, depending on whether it is an endothermic or expthermic reaction the chemicla reactants start at either high (for exothermic) or low (for endothermic). exothermic start high as you might say the reactants hold alot of energy hence why when the reaction takes place they release the energy. The fact that they release the energy means that when the reaction is finished the products will have lower enthalpy in an exothermic reaction as some energy is lost as heat along the waythe graph physically looks like this:http://www.avogadro.co.uk/h_and_s/bondenthalpy/hdiagrams.gif but you need an understanding of it to draw your own
What profile best describes the reaction C plus 2H2 gives CH4 where delta H is minus 74.9 kJ per mol?
As this is an exothermic reaction, you would draw a line at a high level to represent the reactants, and one lower down for the products. The reaction path would be represented by a line which goes up from the reactants, curves over and goes down to the products.
Why is photosynthesis considered an endergonic reaction in an isolated plant?
low-energy reactants are converted into high-energy products
How is activation energy related to bond energy?
If the bond dissociation energy for reactants is high then activation energy required for the reaction also will be high.
What does the statement a high equilibrium product constant mean?
High Kp ( equilibrium constant of product) means that the reaction favors the product formation. More products are formed.
Does endothermic have high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.

What are the reactants and products in the processs of photosynthesis?
Photosynthesis uses the energy of sunlight to convert water and carbon dixode into high-engery sugers and oxygen.Recants-carbon dixode and waterProducts-high-energy sugars and oxygen
Energy transformation in the refrigerator?
The Energy Transformations in a Fridge are Electrical Energy, Mechanical Energy, Thermal Energy.I had to do this for science at high school in year 7 and this is the answer!hope it helps
What problems must be overcome before fusion can be used to produce energy?
achieving high temperatures and containing the plasma reactants
Why is high pressure necessary for making ammonia?
When producing ammonia, there is not a 100% change from reactants into products. In fact, around half of the reactants will change into ammonia, and then equilibria is reached and the amount of ammonia will stay the same. Increasing the pressure shifts the equilibria, so that more ammonia is produced when an equilibria is reached, making the process more efficient. Hypothetical example: 1 litre of reactants (normal pressure) -----> 0.5 litre reactants and 0.5 litre ammonia 1 litre of reactants (high pressure) -------> 0.2 litre reactants and 0.8 litre ammonia
Are there other high energy products of glycolysis?
pyruvate, atp, nadh
