Description: A sample of C2 H2( g) has a pressure of 7.8 kPa. After some time, a portion of it reacts to form C6 H6(g) . The total pressure of the mixture of gases is then 3.9 kPa. Assume the volume and the temperature do not change. What fraction of C2 H2( g) has undergone reaction?

step 1 Start this problem, we write the chemical equation. 3C2H2 forms C6H6. And we want to find the mo

Question

A sample of $\mathrm{C}_{2} \mathrm{H}_{2}(\mathrm{~g})$ has a pressure of $7.8 \mathrm{kPa}$. After some time, a portion of it reacts to form $\mathrm{C}_{6} \mathrm{H}_{6}(g) .$ The total pressure of the mixture of gases is then $3.9 \mathrm{kPa}$. Assume the volume and the temperature do not change. What fraction of $\mathrm{C}_{2} \mathrm{H}_{2}(\mathrm{~g})$ has undergone reaction?

Step 1

Three molecules of $\mathrm{C}_{2} \mathrm{H}_{2}$ combine to form one molecule of $\mathrm{C}_{6} \mathrm{H}_{6}$. This can be written as: \[3\mathrm{C}_{2} \mathrm{H}_{2} \rightarrow \mathrm{C}_{6} \mathrm{H}_{6}\] Show more…
