The overall reaction for photosynthesis can be represented by the following equation:
Svet_ta [14]

B & C

Explanation:

Because the forward reaction results in a positive change in enthalpy, this reaction is endothermic – it takes energy from the environment. Therefore, the forward reaction will be favored if there are an increase n temperatures

Forward and reverse reactions are usually balanced. Removing a product (C6H12O6 in this case) as it is formed, favors the forward's reaction.  This is because the process that results in a reduction in pressure of the system is favoured in the reaction.

A gas exerts a pressure of 0.62 atm. Convert this to kPa and mmHg. Be sure to show your work.
IRINA_888 [86]

Answer:

The answer to your question is 0.62 atm = 62.82 kPa = 471.2 mmHg

Explanation:

Data

P = 0.62 atm

P = ? kPa

P = ? mmHg

Process

1.- Look for the conversion factor of atm to kPa and mmHg

 1 atm = 101.325 kPa

1 atm = 760 mmHg

2.- Do the conversions

                  1 atm ----------------- 101.325 kPa

                  0.62 atm ------------  x

                   x = (0,62 x 101.325) / 1

                  x = 62.82 kPa

                   1 atm ------------------ 760 mmHg

                   0.62 atm ------------  x

                   x = (0.62 x 760)/1

                   x = 471.2 mmHg
