🤓 Based on our data, we think this question is relevant for Professor Cox's class at CLEMSON.

Solution: Complete the expressions for the rate of appearance of products and the rate of disappearance of reactants in each of the following reactions. NOTE: add only minus signs and fractions where appropriate.a) Cl2O2(g) → 2ClO(g)b) N2O5(g) → NO2(g) + NO3(g)

Problem

Complete the expressions for the rate of appearance of products and the rate of disappearance of reactants in each of the following reactions. NOTE: add only minus signs and fractions where appropriate.

a) Cl2O2(g) → 2ClO(g)

b) N2O5(g) → NO2(g) + NO3(g)

Solution
  • In writing expressions, the change of concentration will be divided by the change in time multiplied by their coefficient.

  • Remember that for rate of disappearance, the reactant side will have a negative sign while for rate appearance, we use positive sign.
