Answer:
I'm very sure it's thermal energy.
Explanation:
Answer:
The correct option is (a).
Explanation:
We need to find the product of given numbers.
First number = 29.5
Second number = 240
Product of two numbers = 29.5 × 240
=
Zeroes from numerator and denominator get cancelled.
So,
Hence, the correct option is (a).
Answer:
23 and 56 minutes or 24 hours
Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes, and 4 seconds with respect to other, distant, stars. Earth's rotation is slowing slightly with time; thus, a day was shorter in the past
To solve this we need to have knowledge of differential rate law which relate the rate to the concentration and time. Therefore, the rate of overall reaction is 1x10⁻²M/s.
<h3>
What is differential rate law? </h3>
A differential rate law represents the rate of a reaction . According to this rate is directly proportional to changes in the concentration of reactants and inversely proportional to specific interval of time. There is another expression of rate law which is integrated rate law which is just opposite of differential rate law.
The given equation is
2NO + O 2NO
(1/2) Rate of disappearance of NO= rate of disappearance of C= (1/2)rate of appearance of NO= rate of overall reaction.
(1/2)rate of appearance of NO= rate of overall reaction.
rate of appearance of NO=2x10⁻²M/s.
Substituting the values in above equation
(1/2)×2x10⁻²M/s = rate of overall reaction.
rate of overall reaction= 1x10⁻²M/s
Therefore, the rate of overall reaction is 1x10⁻²M/s.
