Question

7, which chemical equation has Kc Kp? A. CH,(g) + 2 H2O(g) CO2 + 4 H2(g) B. 2 NO(g) N, (g) + O2(g) C, 2 SO2(g) + 02 (g) 2 SOg(g) D. PF3 (g) + F2 (g) PFs(g) 8. Which equilibrium shifts the right side (products) upon a increase in volume? A. 2C0(g) + O2 (g) 2 CO2(g) B. 2 NO(g) N, (g) + O2(g) C. 2CH4(g) + 4 H20(g) 2CO2 + 8 H2(g) D. Fe(s) + CO2(g) FeO(s) +CO (g) For the reaction, H2(g) + 12(g) 2H1(g), Kc = 2.00 at a particular temperature. A reaction mixture at this temperature initially contains all three gases in equal concentration. Which is true of the reaction mixture? 9. A. Q K the reaction proceeds toward the reactants

Explanation / Answer

Ans 7 B) 2NO(g) = N2 (g) + O2 (g)

Kp = Kc (RT)n

Where n is the difference in the number of moles of reactant and products.

The reaction in B has 2 moles in each reactants and products such that the difference in moles is equal to 0.

So here kp = kc(RT)0

kp = kc
