Bobby found that water has a high boiling point and concluded this was because water intermolecular forces. Based on the data, i
Art [367]

Yes, Bobby is correct

Explanation:

Anomalously high boiling point of water is as a result of the intermolecular forces between the molecules of water.

The intermolecular forces found in water are the very strong hydrogen bonds.  The bulk of the physical properties of matter are due to the intermolecular forces that they possess.

  • Hydrogen bonds are stronger than van der waals forces and they are more effective in binding molecules together into larger units.
  • Substances whose molecules join via hydrogen bonds have higher boiling points i.e lower volatility than those with van der waals forces.
  • Hydrogen bond is actually an electrostatic attraction between hydrogen atom of none molecule and the electronegative atom(O or N or F) of a neighboring molecule.

2 H2 + 2 NO → N2 + 2 H2O the observed rate expression, under some conditions, is: rate = k[NO]2 Which of the following mechanism
guapka [62]

Explanation:

Rate law is defined as the rate of a reaction is directly proportional to the concentration of reactants at constant temperature.

               Rate \propto [\text{concentration of reactant}]^{n}

                                  = k [\text{concentration of reactant}]^{n}

where,     k = rate constant

                n = order of reaction

For the given reaction, 2H_{2} + 2NO \rightarrow N_{2} + 2H_{2}O

Hence, its rate will be as follows.

                   Rate = k[H_{2}][NO]

Also, it is known that slowest step in a chemical reaction is the rate determining step.

Hence, for the given rate law correct reaction is as follows.

Step 1 : H_{2} + NO \rightarrow N + H_{2}O (slow)

Balancing this equation it becomes H_{2} + 2NO \rightarrow N_{2}O + H_{2}O (slow)

Step 2: N_{2}O + H_{2} \rightarrow N_{2} + H_{2}O (fast)
