A Levels Chemistry

Two bulbs R and S, connected by a mercury manometer, are held in a thermostat, as shown. The
volume of R is twice that of S. R contains gas, X, at the same pressure as the nitrogen in S.
R
nitrogen
- thermostat
-manometer
'mercury
When the temperature is increased, which gases in bulb R would cause the mercury level in the
right-hand limb of the manometer to rise?
1 an equilibrium mixture N2F4(g) = 2NF2(g); AH positive
2
an equilibrium mixture CH;NC(g) = CH;CN(g); AH negative
