Tardigrade Admin · Accepted Answer

Correct answer is (a) exothermic

Q. Ef​= activation energy of forward reaction Eb​= activation energy of backward reaction Et​= threshold energy The activation energies for forward and backward reactions of a chemical reaction are 30.5 and 45.4kJmol−1 respectively. The reaction is

exothermic

endothermic

neither exothermic nor endothermic

independent of temperature

Correct answer is (a) exothermic

Q.
$E_{f} =$ activation energy of forward reaction
$E_{b} =$ activation energy of backward reaction
$E_{t} =$ threshold energy
The activation energies for forward and backward reactions of a chemical reaction are $30.5$ and $45.4 k J m o l^{- 1}$ respectively. The reaction is
