half reaction in photosysthisis

Half Life of a Reaction - Half life of a reaction is defined as the time required for reducing the concentration of a reactant to half its initial value. It is denoted as t 1 / 2 . As discussed before, the t 1 / 2 of a zero order reaction ..

The net cell reaction can be obtained by adding these two equations...

Example 6: A first order reaction is 40% complete in 50 minutes. What is the rate constant? In what time will the reaction be 80% comple..

The Concept of Half-cell - A galvanic cell consists of two electrodes dipping into the same or two different electrolytes. No reaction takes place until a conducting wire joins the two electrodes. Once, a chemical reaction takes place at each electrode, electron transf..

Artificial Nuclear Reactions - Radioactivity is broadly classified into two categories: a) Natural radioactivity and b) Artificial or Induced radioactivity. If a substance emits radiations by itself, it is said to possess natural radioactivity. If a substance does not possess radioactivit..

fig 6.9 - Linear form of a first order reaction A special feature of a first order reaction is the half life (t 1 / 2 of the reaction. When the reaction has proceeded half way then [A]=[A] o /2. On substitution of this value in the integra..

Example 9: A first order reaction has k=3 x 10 - 6 s - 1 at 5/3 K. The reaction is allowed to run for five hours. After this time interval what percentage of the initial concentration would have changed into products? What is the half-life of the reaction..

The two half-cell reactions are written in such a way that the reaction taking place at the left hand electrode is written as an oxidation reaction and that taking place at the right electrode is written as reduction reaction..

Measurement of Electrode Potential - The absolute value of single electrode potential cannot be determined because the oxidation half reaction cannot take place without the reduction half. To overcome this difficulty the standard hydrogen electrode (SHE) is taken as th..
