Question

The activation energy for the reaction no2(g) co2(g)⟶no(g) co(g) is ea = 350 kj mol−1 and the change in enthalpy for the reaction is δh = -325 kj mol−1 . what is the activation energy for the reverse reaction?

Answer 1

The activation energy for the reverse reaction can be calculated using the equation Ea(reverse) = Ea(forward) - ΔH. Substituting the given values, we get Ea(reverse) = 675 kJ/mol.

Step-by-step explanation:

The activation energy for the reverse reaction can be determined by using the fact that the activation energy for the forward reaction is 350 kJ/mol. The activation energy for the reverse reaction can be calculated using the equation:

Ea(reverse) = Ea(forward) - ΔH

Substituting the given values, we get:

Ea(reverse) = 350 kJ/mol - (-325 kJ/mol)

Ea(reverse) = 675 kJ/mol
