An unknown gas effuses at a rate that is 0.397 times that of nitrogen (N2) gas at the same temperature Assume the molar mass of N2 is 28.02 g/mol. What is tr unknown gas in g/mol? Write your answer in decimal form (NOT scientific notation) using 3 significant figures.
Consider this exothermic reaction at equilibrium. 4 NH3(0)3 02(0) 2 N₂(0)+H₂O) Predict whether the reaction will shift loft (L). shift right (Ft), or remain unchanged (U) after each disturbance Type L. R. or U for your answers (a) Volume of the reaction mixture is increased L (b) NH3 is added to the reaction mixture: R (0) The reaction mixture is cooled down: R (d) H₂O is removed from the reaction mixture.
