Answer:6
Step-by-step explanation:
We apply arrhenius equation to solve this problem which relates Kc to the change in temperature and that <span>ΔH° is the constant. The arrhenius eqn is :
ln (Kc2)/ ln (Kc1) = </span><span>ΔH°/R * [(1/T1)- (1/T2)] where T is in kelvin.
Thus,
</span>ln (0.575)/ ln (0.405) = <span>ΔH°/8.314 * [(1/(40+273)- (1/(90+273)]
</span><span>ΔH° = 11566.81 J/mol</span>
Answer:
25w+200>750
Step-by-step explanation:
Lawrence gets 25 cards a week, so you can mark this as 25w.
Next, he also started with 200 from his father, so you can add +200.
Lastly, you're calculating how many weeks it would take until he had over 750 cards. So the inequality would be >750.
Add them all up and you get 25w+200>750.
