Answer:
There are four laws of thermodynamics that define fundamental physical quantities (temperature, energy, and entropy) and that characterize thermodynamic systems at thermal equilibrium.
Explanation:
The equation N2+H2= NH3 is balanced. This is because N2 + 3H^2 ➡️ 2NH^3
Answer:
The independent variable is what you change in the experiment.
Explanation:
The independent determines the dependent variable.
Force is a strength or energy as an attribute or physical action or movement, motion is the action or process of moving or being moved
Answer:
Keep temperature constant and increase the pressure of the reaction. The rate of reaction increases.
Explanation:
First of all, the question is asking us to design an experiment to investigate the effect of pressure on the rate of reaction hence the pressure can not be held constant since it is the variable under investigation. This eliminates the first option.
Secondly, increasing the pressure of the reaction means that particles of the gas collide more frequently leading to a greater number of effective collisions and a consequent increase in the rate of reaction according to the collision theory.
Hence the answer above.
