A reaction inside a cylinder with a movable piston causes a volume of a gas to c

Question

A reaction inside a cylinder with a movable piston causes a volume of a gas to change from 11.5 L to 17.0 L by a chemical reaction against a external pressure 0.975 atm. Calculate the work(w) done in joules and then in kJ (1 atm-L = 101J). What is the sign of w? Negative or positive? How much work is done by a surrounding on a system if the volume decreases from 14.5 L to 7.0 L by extering a constant pressure of 5.0 atm? Calculate the work (w) done in joules (J) and then in kJ (1 atm-L = 101J). What is the sign of w? Negative or positive? Calculate heat in kilojoules (kJ) released or absorbed by decomposition of 43.5 g of Fe_2O_3 In the following reaction of decomposition. Determine if the reaction is endothermic . exothermic. Calculate value of DeltaH for the following reaction by rewriting reactions.
