If the temperature increases the pressure increases. If the temperature decreases the pressure decreases I hope this helped
a) First, to get ΔG°rxn we have to use this formula when:
ΔG° = - RT ㏑ K
when ΔG° is Gibbs free energy
and R is the constant = 8.314 J/mol K
and T is the temperature in Kelvin = 25 °C+ 273 = 298 K
and when K = 4.4 x 10^-2
so, by substitution:
ΔG°= - 8.314 * 298 *㏑(4.4 x 10^-2)
= -7739 J = -7.7 KJ
b) then, to get E° cell for a redox reaction we have to use this formula:
ΔE° Cell = (RT / nF) ㏑K
when R is a constant = 8.314 J/molK
and T is the temperature in Kelvin = 25°C + 273 = 298 K
and n = no.of moles of e- from the balanced redox reaction= 3
and F is Faraday constant = 96485 C/mol
and K = 4.4 x 10^-2
so, by substitution:
∴ ΔE° cell = (8.314 * 298 / 3* 96485) *㏑(4.4 x 10^-2)
= - 2.7 x 10^-2 V
Answer:
Explanation:
The answer choices are:
<h2>Solution</h2>
You must use the conversion factors to convert J to kcal.
Dividing both sides by 4.184J:
⇒ 1 = 1cal/4.184J
Dividing both sides by 1,000 cal
⇒ 1 = 1kcal / 1,000 cal
Mutiply<em> 578J</em> by the conversion factors to find <em>kcal</em>:
Notice how the units J and cal cancel to yield kcal at the end.
C.) protons , the nucleus contains 2 subatomic particles , one protons & neutrons ( protons have a + charge & neutrons have no electrical charge
Count the atoms of each element in the reactants and the products.
Use coefficients; place them in front of the compounds as needed.
