Question

False True False 3. According to Collision Theory, surface area is directly related to reaction rate True 4. According to Collision Theory, reaction temperature is indirectly related to reaction rate 5. Determine the equilibrium constant K for the following reaction: H(aq) + OH (aq) = H2O (1) Koq = 6. Determine the value of K, for the reaction CH4 (g) + 2H,S(g) = where [CH] = 0.0005M, [HS] =0.065M, [CS2] = 0.0025M, [H2) = 0.126M CS, (g) + 4H, (g) + Heat [This reaction applies to Question #7: 2C2H2 (g) + 502 (g) + heat 4CO2(g) + 2 H2O(g) 1 7. State in which direction (f. → or no effect) the above reaction will proceed in response to the following changes: a. Decrease in gas pressure b. Increase in concentration of CO, c. Decrease in Temperature d. Addition of a catalyst 8. Write the balanced chemical reaction that produced the following key expression and where H20 (1) is also a reactant: Y [CH C00 (aq)][H0° (aq)] [CH,COOH(aq)]

Answer 1

In generally surface area is more rate of the reaction is more . ci Answer is true - If we If we increase lary decrease the temperature rate of the reaction changes. Rate of reation directely related to the Temperature. & Answer is False keq = [products] [Reactants] Given yt (aq) + 6H (91) = Hoole) In generally liquids and solids concentration=1 Keq = Inty Com]
