A) \[-100R\]
B) \[-137.5\text{ }R\]
C) \[-375R\]
D) None of these
Correct Answer: C
Solution :
[c] \[\Delta H=({{n}_{1}}{{C}_{p,{{m}_{1}}}}+{{n}_{2}}{{C}_{p,{{m}_{2}}}})\Delta T\] \[=\left( 0.5\times \frac{7}{2}R+0.5\times 4R \right)(-100)\] \[=-375\text{ }R\]You need to login to perform this action.
