Answer: 1. All of these
Explanation:
The rate of a reaction depends on following factors:
1. increasing the concentration of reactants: means there is more particles of reactants per unit volume.Thus more particles can collide and hence the rate of reaction increases.
2. increasing the temperature- the particles move faster and undergo more collision which leads to an increase in the rate of the reaction.
3.adding an appropriate catalyst: addition of catalyst lowers the activation energy and thus more reactants can cross the energy barrier. Thus it leads to formation of more products hence an increase in the reaction rate.
Thus the rate of a reaction can be increased by all of these.
Answer: A. aldolase
Explanation:
Phosphofructokinase, is an enzyme which is vital in the regulation of fermentation. It is involved in the glycolysis process.
When it experiences a mutation that was being interfered with the substrate binding, we should note that the enzyme that is going to be most immediately impacted in terms of accessing substrate is aldolase.
Balanced equation : 2Na+I₂⇒2NaI

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
• 1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
• 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
• 3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction
Na+I₂⇒NaI
aNa+bI₂⇒NaI
Na, left=a, right=1⇒a=1
I, left=2b, right=1⇒2b=1⇒b=0.5
Equation becomes :
Na+0.5I₂⇒NaI x 2
2Na+I₂⇒2NaI
Answer:
f = 1.87 × 10¹⁹ s⁻¹
Explanation:
Given data:
Wavelength of light = 1.6 ×10⁻¹¹ m
Frequency of light = ?
Solution:
Formula:
speed of light = wavelength × frequency
Frequency = speed of light / wavelength
speed of light = 3× 10⁸ m/s
Now we will put the values in formula:
Frequency = speed of light / wavelength
f = 3× 10⁸ m/s / 1.6 ×10⁻¹¹ m
f = 1.87 × 10¹⁹ s⁻¹
