solution:
Thermodynamically favorable reaction is the products, because the reaction occurs spontaneously, without the need for energy to be added.
Because a reaction is thermodynamically favoured does not mean that it will be a fast reaction. So 'yes' they always proceed but possibly infinitesimally slowly. Temperature is the most common way of quickening a reaction. Of course a catalyst also does so but this generally by changing the way the reaction occurs, i.e. the mechanism is different using a catalyst but the product is the same. Enzymes are natures catalysts, in synthetic chemistry (and in you car exhaust) metal based compounds are often used.
All reactions have an activation energy EaEa between reactants and products and a small increase in the size of this can slow a reaction exponentially. Experimentally, the rate constant is generally found be of the form k=k0exp(−Ea/RT)k=k0exp(−Ea/RT), which is the Arrhenius equation, with R the gas constant and T the temperature in Kelvin

Correlation is the measure of the similarity in the trend of two variables or between the pattern of functional change between any two variables. A high correlation indicates that one variable follows the same pattern as the other variable does. However through correlation, one cannot say that the two variables are functionally related to each other. Example, pattern of weather change and change in population of humans. These two are not related but similarities in their pattern of change will wrongly indicate that there's a relation between the two. Similarly between marital satisfaction and sexual frequency, a correlation may mean that one varies like the other. However, marital satisfaction is also strongly depending on economical situation of the subjects, behaviour, complex emotions, etc. And the order of these variables will influence the marital satisfaction. Her findings are not useful in establishing any relationship between the two.

The chloroplast is where photosynthesis takes place. Inside you have your two reactions taking place. You have light dependent reaction and the Calvin cycle. This produces energy for the cellular activities of the cell (glucose and ATP).
