Calculate the ratio of the effusion rate of oxygen (O2) to that of carbon dioxide gas (CO2). Express your answer in decimal form and calculate your answer to at least four sig figs. 4.690 Graham's Law of Effusion is: rate/ratez - (M/M)2 where M - molar mass A cylinder with a moveable piston contains 92g of Nitrogen. The external pressure is constant at 1.00 atm. The initial temperature is 200K. When the temperature is decreased by 70 K, by putting...
what’s the difference between molar ratio and stoichiometric ratio? how do you calculate both for the reaction 2 H2 + O2 —> 2 H2O

The H2/CO ratio in mixtures of carbon monoxide and hydrogen (called synthesis gas) is increased by the water-gas shift reaction CO(g)+H2O(g)⇌CO2(g)+H2(g), which has an equilibrium constant Kc=4.24 at 800 K. Part A Calculate the equilibrium concentrations of CO2, H2, CO, and H2O at 800 K if only CO and H2O are present initially at concentrations of 0.129 M . Express your answers using three decimal places separated by commas. Hi I don't know how to solve this problem. Please explain...

Under the right conditions, water dissociates into hydrogen and oxygen. H20 (q) = H2(g) + O2(g) Given the following equation, calculate, to 3 significant figures, the equilibrium constant, ko for water at a pressure, p. of 1.93E5 Pa when 0.4% of the water has dissociated. The degree of dissociation is a. Note that the 112 and 3/2 are powers in the equation below. Nou do not need to supply the units with your answer Kp - (10.5p). (1-a):(1+0.5-a) 2
