A velocity vs time graph is a graph that shows the relationship between the velocity of an object over time. is plotted on the x
S_A_V [24]
A graph shows a relationship between two variables: independent and dependent. The dependent variable is in the y-axis, while the independent variable is in the x-axis. When it says, plot velocity against time, that means that velocity is in the y-axis in meters per second, and time is in the x-axis in seconds. 

An example of a velocity vs time graph is shown in the attached picture. In this example, the motion is in constant acceleration. This is because it is linear, thereby, the slope is constant. If you want to find the instantaneous velocity at a certain time, create a vertical line from the x-axis until it reaches the diagonal line. Then, draw a horizontal line towards the y-axis to know the value of the velocity.

28. What is the heat of reaction for the forward reaction?
ValentinkaMS [17]

Answer:

Check Explanation

Explanation:

The Heat of reaction for the forward reaction is defined as the amount of heat given off or absorbed while the forward reaction is taking place. Mathematically, the heat of reaction for the forward reaction is given as the heat content/heat of formation/Enthalpies of the reaction's products minus the heat content/heat of formation/Enthalpies of the reaction's reactants.

ΔH°run = H°(products) - H°(reactants)

When the heat of reaction is negative, the reaction is said to be exothermic and when it is positive, the reaction is said to be endothermic.

Hope this Helps!!!
