Draw the product that is formed when the compound shown below is treated with an excess of hydrogen gas and a platinum catalyst.
hexene
1 answer:
<span>When the hexene is treated with an excess of hydrogen gas and a platinum catalyst, the product formed is hexane.
Hexene is an unsaturated hydrocarbon. Hexene when treated with H2 gas, in presence with Pt catalyst, the double bond is broken. This results in generation of saturated hydrocarbon i.e. hexane. </span>

Answer:
The correct answer is 312.3 K
Explanation:
In order to solve the problem, we use the modified Arrhenius equation which comprises two rate constants (k) and two temperatures (T):
Where Ea is the activation energy (37.4 kJ/mol= 37400 J/mol), R is the gases constant (8.31 J/K.mol), k₁ and k₂ are the rate constant. We know k₁ (0.0160 s⁻¹) and from the problem, k₂ is twice k₁, so k₂= 2 x k₁= 2 x 0.0160 s⁻¹= 0.032 s⁻¹). Finally, T₁= 25ºC + 273 = 298 K. We introduce the data in the equation and calculate T₂:
T₂= 312.33 K
