No credit if work is not shown. Show all steps involved. Substitute in equations along with units. Report final answers with appropriate units and round off to appropriate # sig. figs. 1) A chemical reaction is performed in a flask that is connected to a piston. Heat is allowed to enter or escape this system, but matter cannot. The reaction absorbs 890 J of heat from the surroundings and the gas produced pushes the piston upward against a constant external pressure of 1.5 atm so that the volume of gas changes from 0.95 L to 2.5 L (a) Determine the values of q and w (in Joules) along with the sign. 1 L-atm = 101.3 J The piston is pushed upward. (b) Determine the values of AH and AE values for this reaction. (Hint: Write the equation for AE in terms of heat and work. Hint for AH: This is a constant pressure system. At constant pressure, AH =
