What is the rate of a reaction if the value of k is 0.01 A is 2 M and B is 3 M?
.72
Is a feet in 2 seconds as a unit rate?
Yes, but it is customary to express it as 2 seconds per foot. The denominator - or second measure - usually takes the value 1 in a unit rate.
What is the future value of 1000 dollars in 5 years at interest rate of 5 percent compounded semi-annually?
The first responder posted this response:$1,280.08====================================The next responder posted this response:Assuming the 5% interest rate is the nominal annual rate, the first step is to calculate the effective interest rate.ieffective = (1+r/m)m - 1where r is the nominal rate (.05) and m is the compounding periods per year (semiannual = 2 compoundings per year).ieffective = (1+.05/2)2 - 1 = .0506Simply use this effective rate to solveFuture Value = Present Value * (1+i)nwhere i is the effective interest rate and n is the number of years.F = 1000*(1+.0506)5 = $1280.08
2x-4 equals 12 what is the value of x?
2x - 4 = 12Add 4 to each side:2x = 16Divide each side by 2:x = 8
What does 8x for each value of x mean?
You would multiply that value by 8 for every number. So if x is 2, 8x is 16, if x is 3, 8x would be 18.
What is the rate of a reaction if the value of k is A and B are each 2 M?

What is the rate of a reaction if the value of k is 3 and A and B are each 2 M Rate kA2B?
24 (mol/L)/s
What would happen to the rate of a reaction with rate law ratekNO2H2 if the concentratin of H2 were halved?
Since the reaction is first order with respect to H2, if the concentration of H2 were halved, the rate of the reaction would be halved. This can be seen by entering one for each value in the rate equation, then changing the value of [H2] to 1/2 while keeping the other values the same: The rate changes from 1 to 1/2.
What is the rate of a reaction if the value of k is 0.01 A is 2 M and B is 3 M?
.72
What is the rate of a reaction if the value of k is 0.01 A is 2 M and B is 3 M Rate kA3B2?

.72 (mol/L)/s
What is the rate of a reaction if the value of k is 0.1 A is 1 M and B is 2 M?
0.4 (mol/L)/s
What is the rate constant of a reaction if rate 0.2 (molL)s A and B are each 3 M m 1 and n 2?
7.4 10-3
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
The concentration of both A and B was doubled the reaction rate also doubled What is the rate law for this reaction?
Rate = k[A]2[B]0
What is true of the value of an intermediate reaction?
It is multiplied by 2 if the intermediate reaction is multiplied by 2
What would happen to the rate of a reaction with rate law rate k NO 2 H2 if the concentration of NO were halved?
The reaction rate would decrease
