As you increase the force applied to a rolling ball the acceleration of the ball increases this is an example of what law?
if you increase the force , the mass remaining constant, a new rate of acceleration applies in the order a = f/m from that point (second law)
What according to Newton's second law does an object acted on by a net force will accelerate in the direction of what?
f=ma newtons 2nd law of motion where f is the net force m is mass in kg and a is acceleration in m/s^2 basically the net force is in the direction of the acceleration
How do you convert two meters to feet?
2 meters = 6.561 679 79 feet If you need the mathematical eqation, set it up as a proportion: 1 meter 2 meters ---------- = ---------- 3.280 feet X feet Direct Conversion Formula2 m* 1 ft 0.3048 m = 6.56167979 ft
Newton's second law of motion?
Newton's 2nd law state that the rate of momentum is proportional to the impressed force & the change in momentum takes place in the direction of force. Mathematically , F = dP/dt = m dv/dt + vdm/dt = m dv/dt = ma [for constant mass system dm/dt = 0]
What does the newton second law of motion depend on?
"The rate of change of momentum is directly proportional to the impressed force and acts in the direction in which the force acts" Acceleration "a" varies directly proportional to "F" the impressed force. F = m x a a = F/m
Which equation is an expression of the rate law?
Rate = k[A]m[B]n
What are m and n in the rate law equation rate kAmBn?
They are experimentally determined exponents.
Determine the rate of a reaction that follows the rate law rate kAmBn where k 0.2 A 3 M B 3 M m 1 n 2?
5.4 (apex)
What is the general form of a rate law?
The general form of a rate law is rate = k[A]^m[B]^n, where rate is the reaction rate, k is the rate constant, [A] and [B] are the concentrations of reactants A and B, and m and n are the respective reaction orders for A and B.

What is the rate of a reaction that follows the rate law rate kAmBn if k 0.02 A and B are each 3 M m 2 and n 3?
0.54 (mol/L)/s
Given the rate law shown below find the rate constant when 0.500 M of the hypochlorite ion and 0.0500 M of the iodine ion react to give an initial rate of 0.150 M s?
59 - 60.1 m-1 s-1
What equation shows how rate depends on concentrations of reactions?
The equation is called the rate law equation. For the reaction aA+bB =>cC+dD the rate law would be rate = k[A]^m[B]^n where k is the rate constant and m and n are the "order" with respect to each reactant. m and n must be determined experimentally and may or may not be the same as the coefficients a and b.
Given the rate law shown below find the rate constant when 0.500 M of hydrogen iodide reacts to give an initial rate of 2.95 10 4 M s?
0.00117 - 0.0012 M-1s-1
