Based on the information given, it has been computed that the activation energy will be 105.8Kj.

<h3>How to calculate activition energy</h3>

From the information given,

T1 = 25 + 273 = 298K

T2 = 35 + 273 = 308J

R = 8.314J/mol

K2/K1 = 4

Therefore,

log(4) = E/(2.303 × 8.314) × [10/(298 × 308)]

= (0.602 × 2.303 × 8.314 × 298 × 308) / 10

= 105.8KJ

Therefore, the activation energy is 105.8KJ.

John bought 15 pines for $3500
Shalnov [3]

Answer:

Explanation:

If John needs to ensure a 40% profit, John needs to sell the pines at a price that would give 40% more money back than he spent.

Since John needs to make back all of the money he spent, plus another 40%, John needs to get back 140% of what he spent.

140\% = 1.40

John spent $3500.

140% of $3500 is $4900.

So, John must bring in $4900 (revenue) selling all 15 pines to achieve a 40% profit.

However, the question asks for the price of a single pine.  To find the unit price of a single pine, divide the total revenue by 15.

\frac{\$4900}{15pines}=\frac{\$326.\bar{6}}{pine}=\$326.66 \text{ per pine}
