We can get ΔG from this formula:
ΔG = -R*T*(㏑K)
when K = p(N2O4) / p(NO2)^2
we have P(N2O4) = 1.64 atm
and P(NO2)^2 = 0.38 atm
by substitution:
=1.64 atm / (0.38)^2
= 11.36
and R = 8.314
and T = 298 K
so by substitution on ΔG formula:
∴ ΔG = 8.314 *298 *(㏑ 11.36)
= - 6020.7
I think It's a value that depends on another
Answer:
%age Yield = 42.9 %
Explanation:
Percentage Yield is defined as the actual yield divided by theoretical yield. It is given as,
%age Yield = Actual Yield / Theoretical Yield × 100 --- (1)
Also,
Actual Yield is the amount of desired product which is obtained after an experiment is completed. We can also call it the real yield which is obtained practically. While, theoretical yield is the yield which is calculated on paper. Hence, we can say that the actual yield is always less than theoretical yield due to many reasons including reaction conditions and researcher handling problems.
Thus we are given following data;
Theoretical Yield = 1.70 g
Actual Yield = 0.73 g
Putting these values in Eq. 1,
%age Yield = 0.73 g / 1.70 g × 100
%age Yield = 42.9 %
The answer is (B).
Hope this helps :).
