For the reaction N2O4(g) <--> (equilibrium arrows) 2NO2(g), kp = 0.25 at a certain temperature. Calculate the equilibrium pressures of NO2(g) and N2SO4(g) if the initial pressures of the components when placed in an otherwise empty container are as follows initial PNO2 = 0.0 atm Initial PN2O4= 0.040 atm Equilibrium PNO2 = ? atm Equilibrium PN2O4 = ? atm How do I go about solving this?
The balance used to measure the mass of the metal reads low (for example, it reads 19.4 g instead of an actual 19.7 g). How will this error, due to miscalculation of the balance, affect the reported specific heat value for the metal. Explain.
25 cubic centimetres of potassium hydroxide solution were neutralized by 24.0 cubic cenimtre of 1M per decimetre hydrochloric acid. what is the concentration in molar per decimetre of alkali?
Which of the following, when added in equal molar amounts to the AgOH/water mixture, will lead to the greatest concentration of dissolved Ag+ at equilibrium?
has a standard free-energy change of -4.00 kJ/mol at 25 °C. What are the concentrations of A, B, and C at equilibrium if, at the beginning of the reaction, their concentrations are 0.30 M, 0.40 M, and 0 M, respectively
The standard free energy of activation of a reaction A is 89.0 kJ mol-1 (21.3 kcal mol-1) at 298 K. Reaction B is ten million times faster than reaction A at the same temperature
where n increases from zero to fourteen over the series from Lanthanum to Lutetium Select the two ions that have 5 unpaired spins. which 2 would have it?
When no single electronic formula can be drawn for a stable molecule so as to maintain the octet rule and still fit the observed properties, the situation is best described in terms of
H2S (aq) is a polyprotic acid, meaning it can dissociate its hydrogen ion more than once. However, HS- (given its negative charge as well as its extra hydrogen ion) can act as either a base or an acid
How many grams of F2 are needed to produce 237 g of PF3 if the reaction has a 80.4% yield?
The Rice-Herzfeld mechanism for the thermal decomposition of acetaldehyde (CH3CO) is the following below (10 points) (1) CH3CHO ---> CH3' + CHO' (k1) (2) CH3' + CH3CHO ---> CH4 + CH2CHO' (k2) (3) CH2CHO' --->CO + CH3' (k3) (4) CH3' + CH3' --->C2H6..
We had a 0.10 M solution of acetic acid in water. We then placed 2 mL of the 0.10 M solution and 2 mL of toluene into a dropper and mixed. We did some magic and had
