<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
A catalyst is defined as the substance which increases the rate of the reaction without actually participating in the reaction.
This substance decreases the activation energy of the reactants, so as to proceed the reaction at a faster rate by increasing their effective collisions.
It does not affect the concentration of the reactants.
For the given reaction:
If we add NO, which is acting as a catalyst will increase the rate of the reaction to produce the products which is 
Hence, the correct answer is Option A.
Answer:
<h2>10 m/s</h2>
Explanation:
Her average speed can be found by using the formula
d is the distance
t is the time taken
From the question we have
We have the final answer as
<h3>10 m/s</h3>
Hope this helps you
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
Answer:
5.59 g of ClO₂
Solution:
First calculate moles of Cl₂:
According to ideal gas equation,
P V = n R T
Or,
n = P V / R T
Putting values,
n = (1.5 atm × 2.0 L) ÷ (0.0821 atm.L.mol⁻¹.K⁻¹ × 294 K)
n = 0.124 mol of Cl₂
According to equation,
1 mole Cl₂ required = 2 moles of NaClO₂
So,
0.124 mole Cl₂ will require = X moles of NaClO₂
Solving for X,
X = (0.124 mol × 2 mol) ÷ 1 mol
X = 0.248 mol of NaClO₂
And given mass of NaClO₂ equals followinf moles,
n = 15 g ÷ 90.45 g.mol⁻¹
n = 0.1658 mol of NaClO₂
It means we are given with less amount of NaClO₂, hence it is limiting reagent and will control the amount of product formed.
So, According to equation
2 moles of NaClO₂ produced = 67.45 g of ClO₂
So,
0.1658 moles of NaClO₂ will produce = X g of ClO₂
Solving for X,
X = (67.45 g × 0.1658 mol) ÷ 2 mol
X = 5.59 g of ClO₂
