Rate law equation The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction betwe

Studentka2010 [4]

Explanation:

In the following reaction;

aA+bB⇌cC+dD

A and B are the reactants while C and D are the products.

a, b, c and d are regarded as coefficients.

The dependence of the reaction on the concentration of the reactants is given by the rate law.

This is given by;

rate= k [A]^m [B]^n

where

K = Rate constant. Constant for the reaction at that temperature.

m = order of reeaction with respect to A

n = order of reaction with repsect to B

Overall order of reaction is given by m + n

How many moles of HNO3 will be produced 3 NO2+H2O=2HNO3+ NO

valkas [14]

Answer:

2 moles of HNO3

Explanation:

The equation seems to be balanced correctly. The problem is we done know what you started with. We will assume it is 3 moles of NO2.

If that is the case then 2 moles of HNO3 will be produced.

calculate the standard potential arising from the reaction in which NADH is oxidized to NAD and the corresponding biological sta

melisa1 [442]

Answer:

-219.99kJ

Explanation:

The acronym '' NADH'' simply stands for what is known as coenzyme 1 with full meaning of Nicotinamide Adenine Dinucleotide Hydride. This substance is useful in the production of energy. The oxidation reaction of NADH causes it to produce NADP⁺ and the oxygen produces water when it is in the reduction process. The balanced equation for the oxidation reaction is given below as:

NADPH ---------------------------------------------------------------------> NADP⁺H⁺ + 2e⁻.

Also, the balanced equation for the reduction reaction is given below as:

$\frac{1}{2}$ O₂ + 2H⁺ + 2e⁻ --------------------------------------------------------------> H₂O.

It can be shown from the above REDOX reaction that the total number of electrons getting transferred is 2.

The Gibbs energy = -nFE. where n = 2, F = faraday's constant = 96485.3329 C and E = overall cell potential.

The overall cell potential = E[ reduction reaction] - E[oxidation reaction] = 0.82 - (- 0.32 ) = 1.14 V.

Hence, the Gibbs energy = - 2 × 96485.3329 × 1.14 = -219.99kJ
