Chemistry
1 answer:
Inessa [10]3 years ago
8 0

Answer:

D. B, C, A

Explanation:

A. For object A, given the following data;

Mass = 2kg

Net force = 1N

To find the acceleration;

Acceleration = net force/mass

Acceleration = 1/2

<em>Acceleration = 0.5m/s²</em>

B. For object B, given the following data;

Mass = 8kg

Net force = 10N

To find the acceleration;

Acceleration = net force/mass

Acceleration = 10/8

<em>Acceleration = 1.25m/s²</em>

C. For object C, given the following data;

Mass = 7kg

Net force = 7N

To find the acceleration;

Acceleration = net force/mass

Acceleration = 7/7

<em>Acceleration = 1m/s²</em>

Therefore, placing the objects in decreasing order, according to the magnitude of the acceleration they are experiencing is B, C, A

A first order reaction has a rate constant of 0.543 at 25 c and 6.47 at 47
alukav5142 [94]

The activation energy Ea can be related to rate constant (k) at temperature (T) through the equation:

ln(k2/k1) = Ea/R[1/T1 - 1/T2]

where :

k1 is the rate constant at temperature T1

k2 is the rate constant at temperature T2

R = gas constant = 8.314 J/K-mol

Given data:

k1 = 0.543 s-1; T1 = 25 C = 25+273 = 298 K

k2 = 6.47 s-1; T = 47 C = 47+273 = 320 K

ln(6.47/0.543) = Ea/8.314 [1/298 - 1/320]

2.478 = 2.774 *10^-5 Ea

Ea = 0.8934*10^5 J = 89.3 kJ
