Answer:
The answer is explained below:
Explanation:
Given the chemical equation:
N2H4(g)+H2(g)→2NH3(g)
The standard enthalpy of formation is given by the following formula:
ΔH^0 rxn = ∑ B reactants - ∑ product
-187.78 kJ/mol = [( 1x B N-N) + (1 x B N-H ) + (1 x b H-H)] - [ 6 x B N-H]
-187.78 kJ/mol = [( 1x B N-N) +(4 x 391 kJ/mol) + (1 x 436 kJ/mol)] - [ 6x 391 kJ/mol ]
-187.78 kJ/mol = B N-N + (1564 + 436 - 2346) kJ/mol
B = 158.22 kJ/mol
So, in this case the enthalpy of N-N bond is 158 kJ/mol
The rate of product formation by an enzyme-catalyzed reaction would be increased by temperature (until it reaches optimim temperature)
as the temp increases the pressure increases to.
Answer:
Answer:
C
Explanation:
Greenhouse gases allow for sunlight, and the heat radiation to enter the atmosphere, and then prevent it from exiting the atmosphere. Known as the greenhouse effect.
