For a reaction A+B products, H is -84.2 kJ and S is -200 J K^-1. Calculate the highest value of temperature so that the reaction will proceed in forward direction.

Question

Accepted Answer

Correct answer: A. (a) : Given, A+B ⟶ Products H=-84.2 kJ ; S=-200 J K^-1 G= H-T S=(-84.2 10^3)-T (-200 ) For the reaction to be spontaneous, G should be negative. So, highest value of T= 84.2 1000200=421 K

$For a reaction A + B \to products, Δ H is - 84.2 kJ and Δ S is - 200 J K^{- 1} . Calculate the highest value of temperature so that the reaction will proceed in forward direction.$
