<span>Like dissolves like and unlike repels like. This applies to the polarity of the solutions. Polar dissolves polar and non-polar does not mix with polar solutions. In this case, the polar substance that can mix with water. Sugar and salt can be dissolved through agitation. Oil which is nonpolar is immiscible in water. Hence answer is D. </span>

Answer:
K(79°C) = 1.906 E7 s-1
Explanation:
Arrhenius eq:
∴ A = 5.0 E9 s-1
∴ Ea = 16.3 KJ/mol
∴ R = 8.314 E-3 KJ/K.mol
∴ T = 79°C ≅ 352 K ⇒ K = ?
⇒ K(79°C) = (5.0 E9 s-1)e∧[ - (16.3KJ/mol)/(8.314 E-3 KJ/K.mol)(352 K)]
⇒ K(79°C) = (5.0 E9 s-1)e∧(- 5.5697)
⇒ K(79°C) = (5.0 E9 s-1)*(3.811 E-3)
⇒ K(79°C) = 1.906 E7 s-1
