Connecting Slope to Real Life Why do we need to find the slope of a line in real life? The slope of a line tells us how something changes over time.
Equilibrium Description Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible?
What affects the rate of a reaction? Sample Learning Goals Explain why and how a pinball shooter can be used to help understand ideas about reactions. Describe on a microscopic level what contributes to a successful reaction with illustrations. Describe how the reaction coordinate can be used to predict whether a reaction will proceed or slow.
Use the potential energy diagram to determine: The activation energy for the forward and reverse reactions; The difference in energy between reactants and products; The relative potential energies of the molecules at different positions on a reaction coordinate.
Draw a potential energy diagram from the energies of reactants and products and activation energy.
Sketch how the number of reactants and products will change as a reaction proceeds. Explain how they know that a system has reached equilibrium from a graph of number of reactants and products versus time. Predict how raising or lowering the temperature will affect a system in the equilibrium position.
Describe the relative sizes of the forward and reverse rates at equilibrium. Explain what effects whether the equilibrium position favors the products or the reactants. Predict how addition of a reactant or product will affect the forward and reverse reaction rates, and once this new system reaches equilibrium how the reactant and product concentrations will compare to the original system at equilibrium.
Compare graphs of concentration vs.‘Fake news’ or ‘inconvenient truth’? The global community agreed in the Paris Climate Agreement to recognise climate change as man-made and work together on a common response.
In , Linda purchased a house for $, In , the house was worth $, Find the average annual rate of change in dollars per year in the value of the house. The planet's average surface temperature has risen about degrees Fahrenheit ( degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.
4 Most of the warming occurred in the past 35 years, with the five warmest years on record taking place since Not only was the warmest year on. For these 9 talks, the average speaking rate is words per minute.
Two thirds of the talks are clustered in a narrow range between and words per minute. Remember that this average and range do not necessarily apply to all speaking situations.
WND EXCLUSIVE Murder rate for these white farmers 20 times international average South African minority facing genocide incited by government Published: 04/01/ at PM. The slope is the rate of change from one month to the next. Take a look at how this can be solved.
In , Linda purchased a house for $, In , the house was worth $, Find the average annual rate of change in dollars per year in the value of the house. I can write them as an ordered pair. Special Note: If time is.
