Answer: K = 284
Explanation:
Gibbs free energy (DG) = RT(InK)
Where :
R = Gas constant = 8.314J/K/mol = 0.008314KJmol/K
T = temperature in Kelvin = 298K
K = dissociation rate
DG = 14
DG = RT(InK)
14 = 0.008314 × 298 × (InK)
14 = 2.477572 × InK
Ink = (14 ÷ 2.477542)
InK = 5.6507619
K = 284
The result would be: loss of farmland
Answer:
Photosynthesis is considered an endothermic reaction, because during the process of photosynthesis, energy from the sun or sunlight is being absorbed.
Explanation:
Any chemical reactions that absorb heat energy from the surroundings to form products is termed the endothermic reaction.
Answer:

Explanation:
The frequency and the wavelength of a wave are related by the equation

where
v is the speed
f is the frequency
is the wavelength
For the sound wave in this problem, we have
f = 634 Hz (frequency)
(wavelength)
Therefore, the speed of the wave is

The speed of sound in air depends on the temperature according to the equation

where T is the temperature.
In this problem, we know the speed, so we can calculate the temperature:
