Given N2H4 + 7H2O2 → 2HNO3 + 8H2O. If the rate of appearance of HNO3 is...
Consider the following reaction: AB The average rate of appearance of B is given by A[B]At. Comparing the rate of appearance of B and the rate of disappearance of A, we get A[B]/At = * (-A[A]/At). A) +1 B) +2 C) -1 D) +1/2 E) -1/2
The rate of a chemical reaction can be measured as the rate of appearance of any of the products or as the rate of disappearance of any of the reactants. These relative rates of reaction are related through the stoichiometry of the overall reaction. For example, the rate of the reaction shown below can be determined by measuring the initial rate of disappearance of I, -A[I']/At. CIO3 (aq)91 (aq)+ 6 Ht (aq) 31 3 (aq)CI(aq) 3H20 If the initial rate...
