2no + o22 no2 is second order in no and first order in o2. complete the rate law for this reaction in the box below. use the form , where '1' is understood for m, n (don't enter 1) and concentrations taken to the zero power do not appear. rate = in an experiment to determine the rate law, the rate constant was determined to be 9.87×103 m-2s-1. using this value for the rate constant, the rate of the reaction when [no] = 7.86×10-3 m and [o2] = 2.21×10-3 m would be ms-1.

Answer : The value of rate of reaction is

Explanation :

Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

The given chemical equation is:

Rate law expression for the reaction is:

As per question,

a = order with respect to  = 2

b = order with respect to = 1

Thus, the rate law becomes:

Now, calculating the value of rate of reaction by using the rate law expression.

Given :

k = rate constant =

[NO] = concentration of NO =

= concentration of =

Now put all the given values in the above expression, we get:

Hence, the value of rate of reaction is

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
