Question

Which of the following correctly represents the standard enthalpy of formation of ccl4?
(1) C (graphite) + 2Cl2 (l) --- CCl4 (g)
(2) C (graphite) + 4Cl (g) --- CCl4 (g)
(3) C (diamond) + 2Cl2 (g) --- CCl4 (g)
(4) C (graphite) + 2Cl2 (g) --- CCl4 (g)

Answer 1

(4)

It represents correctly as 2Cl2(g) combines with graphite to form carbon tetrachloride.

Answer 2

Answer:

4)c(graphite )+2Cl2(g)___CCl4(g)
