Compare their effusion rate and explain briefly d. Calculate the ratio of their effusion rate. V. A pioneer stuck a 503 gram iron ball at 800 0C(Cp of Fe = 0.450 J/g.K)) into his coffee pot containing 0.250 L coffee. Assuming the density of coffee is 1.10 g/ml and the heat capacity is 4.10 J/g.K, calculate the final temperature of the coffee. VI. a. Calculate the ∆Hrxn for the following reactions: a.1. N 2 (g) + 3 H 2 (g) > 2 NH 3 (g) a.2. 4 NH 3 (g) + 5 O 2 (g) > 4 NO(g) + 6 H 2 O(l) a.3. H 2 (g) + ½ O 2 (g) > H 2 O(g) b. Using Hess’s Law and the information given in part a, calculate the ∆Hrxn for: ½ N 2 (g) + ½ O 2 (g) > NO(g)...
