Suppose 2.00 g azomethane (58.1 g/mol) are placed in a 2.50 L container at 425 degree C and allowed to decompose according to the first order reaction, CH-3NNCH_3 (g) rightarrow C_2H_6 (g) + N_2 (g). Initially, 0.0234 moles of C_2H_6, are produced per second. What is the rate constant?
Consider the following reaction: Ca(s) + 2 H_2O(l) rightarrow Ca(OH)_2(s) + H_2(g) Calculate the heat of reaction based on the following information: 2H_2(g) + O_2(g) rightarrow 2 H_2O(l) DeltaH = -572 kJ/mol CaO(s) + H_2O(l) rightarrow Ca(OH)_2(s) DeltaH = -64 kJ/mol CaCO_3(s) rightarrow CaO(s) + CO_2(g) DeltaH = +178.1 kJ/mol 2 Ca (s) + O_2(g) rightarrow 2 CaO(s) DeltaH = -1270 kJ/mol 13. Acetylene is used in blow torches, and bums according to the following equation: 2 C_2H_2(g) + 5...
