H2(g) + Cl2(g) 2 HCl(g) Which item is being reduced in this reaction? thanks
find the enthalpy change H for this reaction: CH4(g) + Cl2--> CCl4(g)+HCl Using the following Equations: C(s)+H2(g)-->CH4 H= -74.6 kJ C(s) + Cl2(g)--> CCl4 H=-95.7 kJ H2(g)+Cl2(g)--> HCl H=-92.3 kJ
Problem 4 The value of Δ110 is-12.93 kJ mol-1 for the following reaction: 2HI(g)H2(g) +12(9) Assuming that Δ/P is independent of temperature, calculate K at 700 K given that K = 29.1 at 1000K. HINT: You can integrate the Van't Hoff Equation in a VERY similar way as we approached the integration of the Gibbs-Helmholtz equation)
Calculate the heat of reaction AH for the following reaction: H2(g) + Cl2(9) 2 HCl(9) You can find a table of bond energies by using the Data button on the ALEKS toolbar. Round your answer to the nearest kJ/mol. mol
For the unbalanced reaction H2(g)+NO(g) ---> H2O(g)+N2(g): the initial concentrations are 5.25 M H2, 9.00 M NO, and no H2O or N2. At equilibrium, [N2] = 1.75 M. A) Balance the equation using lowest-whole-number coefficients. Be sure to include states of matter in your equation. B) Calculate the value of K under the reaction conditions at equilibrium.
A student determined the value of K for the reaction 2 H2 (g) + O2 (g) → 2 H2O (g) at several different temperatures. The value for ∆S can be determined from: the slope of the curve at 25ºC from a plot of ln K versus T. the y-intercept of the line resulting from a plot of ln K versus T. the y-intercept of the line resulting from a plot of ln K versus (1/T). the slope of the line...
