The time it takes from recognizing a stimulus to the initiation of a muscle response (the muscle response can be recorded using an EMG).
It is the first phase. The light dependent reaction.
In the light reaction phase of photosynthesis, light energy is converted into chemical energy in the form of ATP and NADPH. These energy carriers are then used in the dark reaction phase, also known as the Calvin Cycle, to convert carbon dioxide into glucose. The dark reaction does not require direct light and takes place in the stroma of the chloroplast.
A homogeneous reaction is one in which all reactants and products are in the same phase (e.g., gas, liquid, or solid). This type of reaction is characterized by uniform concentration and temperature throughout the reaction mixture. Examples include aqueous reactions in liquid phase and combustion reactions in gas phase.
If the reaction occurs in the gas phase
A gas released during a chemical reaction is a chemical change.
The centers for control of repetitious or stereotyped motor skills are found in the premotor cortex and the supplementary motor area, located in the frontal lobe of the brain. These areas are involved in planning and coordinating movements, especially those that are learned and repeated over time.
-Fractionated reaction time is divided into two components:·Premotor Reaction time, which is the onset of the stimulus to the onset of the muscle activation. This involves EMG. Pre motor RT is providing someone with an index that shows the processing time to plan and program a response.·Motor RT measures the time that movement time begins. It reflects an electro mechanical delay that is associated with the lag muscle to overcome inertia of the limb.-M-Matthew D. Heath University of Western Ontario
It is the first phase. The light dependent reaction.
Peritectic reaction is a reaction in which two phases (solid and a primary solid phase alpha) in converted into a single phase beta. Differs from eutectic reaction. Unlike eutectic reaction in which a single phase (liquid) is transformed into two solid phases. For eutectic reaction the Eutectic point is the common melting point which is lower than melting points of both individual melting points. This is not true with peritectic reaction.

Phase cancelation
If the reaction occurs in the gas phase
In this reaction, most of the water is produced in the liquid phase.
the total number of molecules in each phase stays constant
If the reaction occurs in the gas phase
Melting is a change of phase.
