Answer:
Explanation:
We want the energy required for the transition:
CO 2 ( s ) + Δ → C O 2 ( g )
Explanation:
We assume that the temperature of the gas and the solid are EQUAL.
And thus we simply have to work out the product:
2 × 10^ 3 ⋅ g × 196.3 ⋅ J ⋅ g − 1 to get an answer in Joules as required.
What would be the energy change for the reverse transition:
C O 2 ( g ) + → C O 2 ( s ) ?
