Answer:
ΔG for overall reaction : -21.3 kJ
Explanation:
Reaction of the conversion of glycerol to glycerol-3-phosphate is unfavorable and thus is coupled with second reaction that involves the conversion of ATP to ADP which is highly energetically favorable.
Reaction 1: Glycerol + HPO₄²⁻ ⇒ Glycerol-3-phosphate + water
Reaction 2: ATP + H₂O ⇒ ADP + HPO₄²⁻ + H⁺
ΔG for reaction 1 : 9.2 kJ (non-spontaneous : Positive value)
ΔG for reaction 2 : -30.5 kJ (spontaneous : Negative value)
The overall coupled reaction is:
<u>Glycerol + ATP ⇒ Glycerol-3-phosphate + ADP + H⁺</u>
<u>ΔG for overall reaction : 9.2 kJ + (-30.5 kJ) = -21.3 kJ</u>
negative sign signifies that the overall reaction is spontaneous.
Answer:
Option A. 0.378M
Explanation:
Data obtained from the question include:
Molarity of acid (Ma) =..?
Volume of acid (Va) = 37.0 mL
Volume of base (Vb) = 56.0 mL
Molarity of base (Mb) = 0.250 M
Next, we shall write the balanced equation for the reaction. This is given below:
HCl + NaOH —> NaCl + H2O
From the balanced equation above,
The mole ratio of the acid (nA) = 1
The mole ratio of the base (nB) = 1
Finally, we can determine the molarity of the acid as shown below :
MaVa/MbVb = nA/nB
Ma x 37 / 0.25 x 56 = 1
Cross multiply
Ma x 37 = 0.25 x 56
Divide both side by 37
Ma = 0.25 x 56 /37
Ma = 0.378M
Therefore, the molarity of the acid, HCl is 0.378M

Answer:
ΔT = 76.5 °C
Explanation:
Given data:
Amount of water = 100.0 g
Energy needed = 32000 J
Change in temperature = ?
Solution,
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Now we will put the values in formula.
Q = m.c. ΔT
ΔT = Q / m.c
ΔT = 32000 j/ 100.0 g × 4.184 j/g. °C
ΔT = 32000 j / 418.4 j /°C
ΔT = 76.5 °C
