Use bond energies to determine which halogen produces the most exothermic halogenation reaction with ethene. the c−f, c−br, and c−i bond energies are 552 kj/mol, 280 kj/mol, and 209 kj/mol, respectively.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
