Answer:True
Explanation:
Light year is the unit of distance and not a unit of time.
Light year is used to measure astronomical distances.
It is defined as the distance which light travels in one year.
The distance which light travels in one year is around 9.46 trillion kilometers
Thus 1 light year = km.
Thus the given statement that A light-year is the distance that light travels in one year is true.
<u>Answer:</u> The value of for given reaction is 0.465
<u>Explanation:</u>
We are given:
Initial concentration of A = 0.650 M
Initial concentration of B = 1.35 M
Initial concentration of C = 0.300 M
Equilibrium concentration of A = 0.550 M
Equilibrium concentration of B = 0.400 M
For the given chemical equation:
<u>Initial:</u> 0.65 1.35 0.30
<u>At eqllm:</u> 0.65-x 1.35-2x 0.30+x
Evaluating the value of 'x'
So, equilibrium concentration of B = 1.35 - 2x = [1.35 - 2(0.100)] = 1.15 M
Equilibrium concentration of C = (0.30 + x) = (0.300 + 0.100) = 0.400 M
The expression of for above equation follows:
Putting values in above equation, we get:
Hence, the value of for given reaction is 0.465
