Question

Determine the change in standard entropy. ΔS°. For the synthesis of carbon dioxide from graphite and oxygen:

Answer 1

Let's see

• ∆S refers to the total change in entropy of system.

Graphite was in solid state and oxygen was in gaseous state.

When they synthesized they converted to gaseous state

• So randomness of particles increases
• So entropy also increases

∆S=+ve
