Part A The rate constant for a second-order reaction is 0.13 M-15-1. If the initial concentration of reactant is 0.26 mol/L, it takes
to 0.09 mol/L
s for the concentration to decrease

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)

State one important difference between a physical change and a chemical change?

Once similarity and one difference between a mixture of elements and a mixture of compounds
