Question

Which energy difference in the energy profile below corresponds to the activation energy for the forward reaction? x y x + y x = y y=x The equilibrium -constant expression depends on the _______ of the reaction. stoichiometry and mechanism mechanism stoichiometry the quantities of reactants and products initially present temperature The expression for K_p for the reaction below is _______. 4 CuO(s) + CH_4(g) rlhar CO_2(g) + 4CU(s) + 2H_2O(g) [Cu]PCO_2 PH_2O^2/[CuO]^4 PCH_4 PCO_2 PH_2O^2/P CuO PCO_2 PH_2O^2/P CH_4 P CH_4/P CO_s PH_2^2 P CH_4/PH_2O^2 PCO_2

Explanation / Answer

Ans 18. A) x

Activation energy is the minimun amount of energy that reactants should possess in order undergo a chemical reaction . The reactants needs to cross this energy barrier which is denoted by x in the graph .

The y line on the graph shows the energy released in the reaction .
