What excerpt? It always helps to include that bit of information when asking a question.
The energy balance for the overall reaction does not determine if the reaction needs energy input to occur, or not. The requirement, or not, for energy input, depends on the activation energy and that is independent of the overall enthalpy change. There is no answer to your question - it could be any, all or none.
6(CO2 + H2O) ---solar energy--> (C6H12O6) + 6(O2)
Oxygen (O2) and glucose (C6H12O6) You can look at the overall reaction of photosynthesis to determine the answer 6CO2 + 6H2O ---> C6H12O6 + 6O2 (reactants) ---> (products)
Photosynthesis is the phenomenon of preparing starch by green plants in the presence of sunlight.
No, since the reaction reaches a max rate depending on the speed of which the Enzyme bonds to the substrate and the speed at which the enzyme catalyzes the reaction to produce enzyme and product (shown below). E + S --> ES (E - enzyme, S - substrate, P - products) ES --> E + P Thus, if each reaction rate is not equal to each other, the rate of the overall reaction is not only proportional to both the concentration of enzyme and substrate.
the molecularity must be equal to the overall reaction order.
Absolutely not.
The reaction in which energy is being released, and the overall energy change (enthalpy) is negative.
There are 12 chapters in the book of Ecclesiastes.

False. Enzymes do not affect the thermodynamics of a reaction. They only lower the activation energy required for the reaction to proceed, thereby increasing the rate of the reaction without changing the equilibrium constant or overall energetics of the reaction.
Rates of reaction can be expressed depending upon their order.For example say you have a reaction between two chemicals and the initial rate for that reaction is known :-when:-The concentration of one of the reactants is doubled and the other reactants concentration remains the same and the overall rate of reaction does not change - reaction is zero orderwith respect to chemical which was doubled.The concentration of one of the reactants is doubled and other reactants concentration remains the same and the overall rate of reaction doubles - reaction is first order with respect to chemical which was doubled.The concentration of one of the reactants is doubled and other reactants concentration remains the same and the overall rate of reaction quadruples - reaction is second order with respect to chemical which was doubled.Zero Orderrate = kFirst Orderrate = k [A] (reaction is 1st order with respect to [A] and 1st order overall)Second Orderrate = k [A][B] (reaction is first order with respect to [A] and first order with respect to[B], reaction is second order overall)rate = k [A]2 (reaction is second order with respect to [A] and second order overall)Orders are simply added together in order to determine the overall order of reaction :-rate = k [A][B][C] would be third order overall and first order with respect to each of the reactantsThere are other orders of reaction, for example 2 and 3 quarter orders and third order reactions, but these are a little more complex.
Ecclesiastes
Ecclesiastes of Erasmus was created in 1535.
A Rose for Ecclesiastes was created in 1963.
The next book after Ecclesiastes is Song of Solomon
The abbreviation for the Book of Ecclesiastes is Ecc.
