at constant pressure, which of these systems do work on the surroundings? check all that apply!!! A(s) +B(g) -------------->2C(g) 2A(g)+3B(g)------------->4C(g) 2A(g)+B(g)--------------->C(g) A(g)+B(g)----------------->3C(g)
At constant pressure, which of these systems do work on the surroundings? A(g) + 2B(g) — 2C(g) A(s) +B(s) — C(g) A(s) + 2B(g) —— C(g) A(g) + B(g) — 3C(g)
Which of the following reactions have a positive deltaSrxn? check all that apply 2A(g)+ 2B(g) ------>5C(g) 2A(g) +2B(g)------->3C(g) 2A(g) +B(s)--------->3C(g) A(g) +2B(g)----------> 2C(g)
