A is the answer because the others don't make sense. B if you put glass over reactants it doesn't change anything in the reaction. C using a solid with a low surface area will actually be doing the opposite, a higher SA will increase the rate of reaction. D decreasing the concentration will decrease the reaction
Count how many protons there is and search up what symbol has this many protons
Answer:
Option A. 1191.49 K
Explanation:
Data obtained from the question include:
The equation for the reaction is given below:
4HCl + O2 —> 2Cl2 + 2H2O
Enthalpy (H) = +280 KJ/mol = +280000 J/mol
Entropy (S) = +235 J/Kmol
Temperature (T) =..?
The temperature at which the reaction will be feasible can be obtained as follow:
Change in entropy (ΔS) = change in enthalphy (ΔH)/T
(ΔS) = (ΔH)/T
235 = 280000/T
Cross multiply
235 x T = 280000
Divide both side by 235
T = 280000/235
T = 1191.49 K
Therefore, the temperature at which the reaction will be feasible is 1191.49 K
I believe it would be C. While D is also a good answer, the question asks for the statement that is most likely true, and there is no absolute guarantee that in 20 years our resource use will be higher than it is now.
