Answer:
energy = 391.902 kJ /mol
Explanation:
given data
wavelength = 305 nm = 305 × m
to find out
average energy
solution
we know speed of light is 3 × m/s
so we find frequency here first by speed of light formyla
speed = wavelength × frequency
3 × = 305 × × frequency
frequency = 9.8360 ×
so energy is
energy = hf
here h = 6.62 × J-s
so
energy = 6.62 × × 9.8360 ×
energy = 6.51 × J
so
energy = 6.51 × × kJ/mol
energy = 391.902 kJ /mol
True
Explanation:
Reaction rates are defined as the change in the concentration of a reactant or product per unit time. During a reaction, the concentration of a reactant decreases exponentially with time while that of a product increases exponentially with time.
Some of the factors affecting reaction rates are:
- Nature of the reactants
- Concentration of the reactants or pressure of gases
- Temperature
- Presence of a catalyst
- Sunlight
- The rate of a reaction is directly proportional to the concentration of the reactants.
- The higher the concentration of a reaction, the faster it proceeds.
