Question

When 1 mol of a gas burns at constant pressure, it produces 2448 J of heat and does 1 J of work.

A) Determine E for the process.

Express your answer as an integer and include the appropriate units.

B) Determine H for the process.

Express your answer as an integer and include the appropriate units.

C) Determine q for the process.

Express your answer as an integer and include the appropriate units.

D) Determine w for the process.

Express your answer as an integer and include the appropriate units.

Explanation / Answer

a)

dE = Q - W

dE = -2448 - 1

dE = -2449 J

heat is negative, since system/reaciton is losing, trnasferring it to the surroundings

b)

since P = constant

dH = Q

dH = -2448 J

c)

as stated before

q = -2448 J

d)

system does to surrounding implies positive sign

W = +1 J
