5. Two reactants combine to form a product in the reaction A + B -&gt; C. The rate of the reaction depends on the concentrations
Rina8888 [55]

Answer:

C. 2.

Explanation:

The total reaction order of this reaction is second order (2). For a second order reaction ,the rate  depends on two variable concentration terms which may or may not be same.

Given that:

Two reactants combine to form a product in the reaction  A + B → C

The above reaction is bimolecular as two molecules are involved in the reaction.

If C_A and C_B are the concentrations of A and B respectively at any time t, then assuming  that the reaction is of first order with respect to both A and B , the overall order is second and the reaction rate is given by:

\mathbf{\dfrac{-dC_A}{dt}=\dfrac{-dC_B}{dt}=k_2C__AC_B}

where;

\mathbf{k_2} = specific rate constant for a second order reaction and becomes the rate of the reaction when both C_A and C_B are unity.

What type of intermolecular forces are present in liquid methanol?
salantis [7]

Answer:

Hydrogen bonds

Explanation:

Hydrogen bonds are bonds formed in polar molecules in which an hydrogen atom is directly joined to a highly electronegative atom such as oxygen or nitrogen or fluorine.

A hydrogen bond is just an electrostatic attraction between a hydrogen atom of one molecule and the electronegative atom of a neighboring molecule.

Methanol has a formula of CH₃OH and the hydrogen bond is between the H and O.
