Answer:
The answer is D. The rate of the forward reaction is greater than the rate of the reverse reaction.
Explanation:
The forward reaction rate was greater than the reverse reaction rate because more product is present at time 2. This is the answer from ap classroom.
Answer:
sorry I don't really know
Answer:
A. The rate of heat transfer through the material would increase.
Explanation:
To calculate the heat transfer in a heat exchanger you decide that there is not heat leakage to the surroundings, that means that magnitude of the two transfer rates will be equal. Any heat lost by the hot fluid, is gained by the cold fluid. The equation that describes this is Q = m×Cp×dT
Where:
heat = mass flow ×specific heat capacity × temperature difference
So if we increase the rate of flow of cooling water and the other variables that ypu can control remain the same, the result is that the rate of heat transfer through the material would increase, as it is stated in option a.
that would be waste exchange
Answer: It would have a high pitch.
Explanation: since the whistle has a high frequency, I can infer that it will have a high pitch.
