Answer:
Explanation:
The collision theory explains why reactions occur between atoms, ions, and molecules. With the increase in temperature, there is an increase in the number of collisions. Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate.
Answer:
I'd say ''B, positive reaction''
Hope this helps ^-^* Sorry if I'm Wrong.
Explanation:
C
I watch the show and it said if you did not know always put c
Answer:
-105 kJ
Explanation:
The enthalpy change of a reaction is the sum of the energy of the bonds of the reactants and the products. The bonds at the reactants are being broken, so it's an endothermic reaction, so the bond energy must be positive.
The bonds at the products are being formed, so the process is exothermic, and the bond energy must be negative. There are being broken 1 N≡N bond and 3 H-H bonds, and are being formed 6 N-H bonds:
Reactants: 945 + 3*432 = 2241 kJ
Products: 6*(-391) = -2346 kJ
ΔH = 2241 - 2346
ΔH = -105 kJ
Explanation:
As it is given that value of equilibrium constant is
.
And, it is known that if the value of K, that is, equilibrium constant is greater than 1 then the reaction is favorable and proceeds in the forward direction.
This means that formation of products is favored then. As a result, concentration of products will be more.
Whereas if value of K is smaller than 1 then reaction is unfavorable and proceeds in the backward direction. As a result, concentration of reactants will be more.
Since, it is given that K =
which is greater than 1. So, it means reaction is proceeding in the forward direction. Hence, concentration of products which is
will be more.
Thus, we can conclude that for the given reaction the equilibrium concentration of the reactants are much smaller as compared to the equilibrium concentration of the product.
