predict the sign of the entropy change for each of the following processes: a) I2(s)---->2I(g) cannot predict negative positive b) 2Zn(s) + O2 (g) ---> 2ZnO(S) cannot predict positive negative c) N2 (g) + O2(g) ---> 2NO(g) negative postive cannot predict
Predict the sign of the entropy change for each of the following processes: (a) I2(s) → 2I(g) positive cannot predict negative (b) 2Zn(s) + O2(g) → 2ZnO(s) positive negative cannot predict (c) N2(g) + O2(g) → 2NO(g) cannot predict positive negative
Consider the reaction: H2(g) + I2(s) = 2HI (g) Given an initial mass of 19.02g H2 an excess of I2 and assuming that all of the reactant is conserved to products and non is lost calculate the mass (g) of HI produced by the reaction?
The equilibrium constant for the reaction: H2(g) + I2(g) <--> 2HI(g) is 54 at 700 K. A mixture of H2, I2 and HI, each at 0.020 M, was introduced into a container at 700 K. Which of the following is true? At equilibrium, [H2] = [I2] = [HI]. No net change occurs because the system is at equilibrium. The reaction proceeds to the left producing more H2(g) and I2(g). The reaction proceeds to the right producing more HI(g). At equilibrium,...
Given that the reaction H2 (g) + I2 (g) <--> 2HI (g) is at equilibrium and the measured concentrations of each component of the reaction are [H2] = 0.22 M, [I2] = 0.22 M, and [HI] = 1.56 M, write the equilibrium expression and then calculate Keq.
A,) ΔG o for the reaction H2(g) + I2(g) ⇌ 2HI(g) is 2.60 kJ/mol at 25°C. Calculate ΔG, and predict the direction in which the reaction is spontaneous. The initial pressures are: PH2 = 3.10 atm PI2 = 1.5 atm PHI 1.75 atm ΔG = kJ/mol b.)The reaction is spontaneous in the forward direction. The reaction is spontaneous in the reverse direction. Cannot be determined.
Consider the following chemical reaction: H2 (g) + I2 (g) 2HI (g) At equilibrium in a particular experiment, the concentrations of H2, I2, and HI were 0.02, 0.021 and 0.160 M respectively. The value of Keq for this reaction is __________.
For the reaction in the previous problem, that is, 2HI(g) ↔ H2(g) + I2(g) Keq = 0.016 Initially a container contains 0.39 M HI and no product. What is the equilibrium concentration of H2?
Given the equilibrium reaction: 2HI(g) H2(g) + I2(g) A sample mixture of HI, H2, and 12, at equilibrium, was found to have [H2]- 1.4 x 102 Mand [HI 4.0 x 102 M. If Keq 1.0 x 10, calculate the molar concentration of I2 in the equilibrium mixture, Enter your answer in the provided box. ]= м
Consider this reaction: H 2 (g)+ I 2 (g)⇌2HI(g) H2(g)+I2(g)⇌2HI(g) A rxn mixture in a 3.73 L flask at a certain temperature initially contains 0.766 g H2 and 96.7 g I 2 I2 . At equilibrium, the flask holds 90.3 g HI . Calculate the equilibrium constant (Kc)(Kc) for the reaction at this temperature. Record your answer using two significant figures.
