A. Mixture and D. Compound
Answer:
52.9 KJmol-1
Explanation:
From;
log(k2/k1) = Ea/2.303 * R (1/T1 - 1/T2)
The temperatures must be converted to Kelvin;
T1 = 25° C + 273 = 298 K
T2= 35°C + 273 = 308 K
R= gas constant = 8.314 JK-1mol-1
Substituting values;
log 2 = Ea/2.303 * 8.314 (1/298 - 1/308)
Ea = 52.9 KJmol-1
Answer would be c! hope i can help
Physically- say their is a block in a road like a crash they change direction to go around.
OR
Mentally- if their is two paths one of right and the other if wrong they may make a bad decision and is on the path of wrong but they want to change. In doing so they are changing direction.
Living things change direction because its normal it keeps things going.
