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

exothermic

B

endothermic

C

neither exothermic nor endothermic

D

independent of temperature

Text Solution

Verified by Experts


`E_f= 30.5kJ mol^(-1)`
`E_r= 45.4 kJ mol^(-1)`
`:' E_r gt E_f`, the reaction is exothermic
`Delta H=E_f-E_r=-ve`

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

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 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

When the activation energies of the forward and backward reactions are equal, then :
