Answer:
The substrate concentration reached Vmax
Explanation:
In this scenerio, further increase in the rate of reaction was prevented because the substrate concentration hit Vmax.
Beyond the Vmax, the substrate can no longer proceed.
- The substrate is the reactant on which the enzyme works on.
- Enzymes are natural organic chemical catalysts.
- Increasing the concentration of reactants is one of the known and proven ways to speed up the rate of reaction.
- Since we have limited amount of enzymes, once they all bound to the substrate, no further increase in the substrate will have an effect on the rate.
- At the optimum reaction point, all the available substrate will bond with the enzyme.
- Beyond this, the enzymes are saturated will not further any reaction.
I think there would be three answers from the choices. The effects that can occur when heat energy is added to a system would be that increase in temperature, <span>change of state and phase change Hope this answers the questions. Have a nice day.</span>
Answer:
is time required to heat to boiling point form initial temperature.
Explanation:
Given:
initial temperature of water, 
time taken to vapourize half a liter of water, 
desity of water, 
So, the givne mass of water, 
enthalpy of vaporization of water, 
specific heat of water, 
Amount of heat required to raise the temperature of given water mass to 100°C:
Now the amount of heat required to vaporize 0.5 kg of water:
where:
mass of water vaporized due to boiling
Now the power rating of the boiler:
Now the time required to heat to boiling point form initial temperature:
Answer:
53.64 m/s
Explanation:
Applying,
a = (v-u)/t............. Equation 1
Where a = acceleration of the car, v = final velocity of the car, u = initial velocity of the car, t = time.
make u the subject of the equation
u = v-at............. Equation 2
From the question,
Given: a = -12 mph/s = -5.364 m/s², t = 10 seconds, v = 0 m/s (comes to stop)
Substitute these values into equation 2
u = 0-(-5.364×10)
u = 0+53.64
u = 53.64 m/s
