Answer: The equilibrium constant for the reaction at 25 °C is 346.7
Explanation:
Formula used :

where,
= standard Gibb's free energy change = -14.50kJ/mol =14500 J/mol
R = universal gas constant = 8.314 J/K/mole
T = temperature = 
= equilibrium constant = ?
Putting in the values we get:



The equilibrium constant for the reaction at 25 °C is 346.7

Answer:</h3>
CuO(s) + H₂(g) → Cu(s) + H₂O(l)
<h3>
Explanation:</h3>
- Assuming the reaction is the reduction of CuO by H₂
- Then the balanced equation for the reaction is;
CuO(s) + H₂(g) → Cu(s) + H₂O(l)
- The equation shows the reducing property of hydrogen gas, such that hydrogen reduces metal oxides such as copper(ii)oxide to the respective metals.
- The law of conservation requires chemical equations to be balanced so as the mass of reactants will be equal to that of products.
- In this case; there is 1 copper atom, 1 oxygen atom and 2 hydrogen atoms on both side of the equation and thus the equation is balanced.
I think it's between B) Benzene and C) Butane
You may feel cold when you touch certain kinds of matter because some matter gives off cold air. I’m NOT SURE
