The aquation of tris(1, 10-phenanthroline)iron(II) in acid solution takes place according to the equation: Fe(phen)32+ + 3 H3O+ + 3 H2O → Fe(H2O)62+ + 3 phenH+ If the activation energy, Ea, is 126 kJ/mol and the rate constant at 30°C is 9.8 × 10-3 min-1, what is the rate constant at 50°C?

Hydrogen bromide will dissociate into hydrogen and bromine gases.               2HBr(g) ↔  H2(g) + Br2(g)                                      ∆H°rxn = 68 kJ What effect will a temperature increase of 50°C have on this system at equilibrium?

At high temperatures, carbon reacts with O2 to produce CO as follows:                             C(s) + O2(g)  —->  2CO(g). When 0.350 mol of O2 and excess carbon were placed in a 5.00-L container and heated, the equilibrium concentration of CO was found to be 0.060 M. What is the equilibrium constant, Kc, for this reaction?

The decomposition of ozone in the stratosphere can occur by the following two-step mechanism:Which species is a catalyst in this mechanism?

Nitric oxide reacts with oxygen to form nitrogen dioxide: 2 NO(g) + O2(g) ⇌ 2 NO2(g) What is Kc’ for the reverse reaction if the equilibrium concentration of NO is 0.300 M, O2 is 0.200 M, and NO2 is 0.530 M at 25°C?

A mixture of carbon monoxide, hydrogen, and methanol is at equilibrium. The balanced chemical equation is: CO(g) + 2 H2(g) ⇌ CH3OH(g). At 250°C, the mixture contains 0.0960 M CO, 0.191 M H2, and 0.150 M CH3OH. What is the value for Kc?
