Explanation: i hope this heps you bye
Just put 2 in front of NaNO3
Answer: 7s
Explanation:
The order of the reaction is 2.
Integrated rate law for second order kinetic is determined using the formula
1/[At]=1/[Ao] +kt
But, [Ao] is the initial concentration = 1.50 mol/L
And [At] is the final concentration = 1/3 of initial concentration =1/3×1.5 = 0.5 mol/L
Rate constant, k = 0.2 L/mol*s
Using the formula
1/0.5=1/1.5+0.2t
Collecting like terms
1/0.5-1/1.5=0.2t
LCM = 1.5
3-1/1.5=0.2t
2/1.5=0.2t
Multiply both sides by 1/0.2
2/1.5×0.2=t
2/0.3=t
t=6.66s
t=7s
Answer:
Second order
Explanation:
We could obtain the order of reaction by looking at the table very closely.
Now notice that in experiment 1 and 2, the concentration of [OH^-] was held constant while the concentration of [S8] was varied. So we have;
a situation in which the rate of reaction was tripled;
0.3/0.1 = 2.10/0.699
3^1 = 3^1
Therefore the order of reaction with respect to [S8] is 1.
For [OH^-], we have to look at experiment 2 and 3 where the concentration of [S8] was held constant;
x/0.01 = 4.19/2.10
x/0.01 = 2
x = 2 * 0.01
x = 0.02
So we have;
0.02/0.01 = 2^1
2^1 = 2^1
The order of reaction with respect to [OH^-] = 1
So we have the overall rate law as;
Rate = k[S8]^1 [OH^-] ^1
Overall order of reaction = 1 + 1 = 2
Therefore the reaction is second order.
The answer that would best complete the given statement above would be the term PHASE. Here is the complete statement. <span>A homogeneous portion of a mixture that is characterized by uniform properties and capable of being separated by mechanical means is called a PHASE. Hope this helps.</span>
