SI unit of specific heat capacity is:
- JmolK^-1
- Jk^-1
- Kj/mol
- Jg^-1 k^-1
As compared to exothermic reaction, formation of activated complex in endothermic reaction requires:
- Equal Ea
- No Ea
- Greater Ea
- Smaller Ea
For Δn=0
- Kp < Ka
- Kp ≠ Ka
- Kp > Ka
- Kp = Ka
If ionic product is less than Ksp then:
- Precipitation will occur
- Solution will be saturated
- No precipitation will occur
- Solution will be super saturated
