In which of the following plots, an endothermic reaction is correctly represented?

Correct answer

3

Step-by-step solution

K_p and T are related as follows : K_p=K_c (R T)^ z_g where, aligned & K_p= Equilibrium constant in pressure terms & K_c= Equilibrium constant in concentration terms. & aligned R & = Gas constant T & = Temperature n_g & = Gaseous moles of products & - gaseous moles of reactants aligned aligned Therefore, K_p T (for another reaction) Thus, the plot between 1 T and K_F shows a downward straight line slope for K_p . Hence, option (d) is correct.
