The activation energies of the forward and reverse reaction in the case of a chemical reaction are `30.5` and `45.4 kJ//mol` respectively. The reaction is:

A

Exothermic

B

Endothermic

C

Neither exothermic nor endothermic

D

Independent of temperature

Text Solution

Verified by Experts

The correct Answer is:
a
`E_(a_(FR))=DeltaH+E_(a_(BR))`,
`:. 30.5=DeltaH+45.4`
`:. DeltaH=-14.9 kJ mol^(-1)`, i.e., exothermic.

The activation energies of the forward and backward reactions in the case of a chemical reaction are 30.5 and 45.5 KJ/mol , respectively . The reaction is:

A colliison between reactant molecules must occur with a certain minimum energy before it is effective in yielding Product molecules. This minimum energy is called activation energy E_(a) Large the value of activation energy, smaller the value of rate constant k . Larger is the value of activation energy, greater is the effect of temperature rise on rate constant k . E_(f) = Activation energy of forward reaction E_(b) = Activation energy of backward reaction Delta H = E_(f) - E_(b) E_(f) = threshold energy The activation eneries for forward and backward reactions in a chemical reaction are 30.5 and 45.4 kJ mol^(-1) respectively. The reaction is
